Introduction
The Cisco AS5300 is a versatile data communications platform that performs two functions in a single modular chassis, depending on the installed feature cards and IOS images:
•
•
The remote access server is intended for Internet service providers (ISPs), telecommunications carriers, and other service providers that offer managed Internet connections and medium to large sites that provide both digital and analog access to users on an enterprise network. By terminating both analog and digital calls on the same chassis simultaneously, the access server provides a clear, simple, and easy migration path from analog dial access services to digital dial access services.
The Cisco AS5300 Voice Gateway is a versatile data communications platform that provides the functions of an access server, router, and digital modem(s) in a single modular chassis. The Cisco AS5300 includes three feature card slots: one holds a T1/E1/PRI feature card, and the other two support modem feature cards or voice digital signal processor (DSP) feature cards. When equipped with modem cards, the Cisco AS5300 serves as a remote access concentrator for dial-up (modem or ISDN) Internet access. When equipped with voice feature cards and Voice IOS, the Cisco AS5300/Voice Gateway serves as a Voice over IP (VoIP) gateway. By using one slot for modems and the other for voice DSPs, the Cisco AS5300 can serve in both capacities. Modem, voice, or fax calls are routed to the appropriate cards/resources via Dialed Number Identification Service (DNIS).
For information on new features and Cisco IOS commands supported by Cisco IOS Release 12.1(5) XM8, see the "New and Changed Information" section and the "Related Documentation" section.

Supported Hardware
Cisco IOS Release 12.1(5) XM8 supports the Cisco AS5300. Table 2 details the supported interfaces.
For detailed descriptions of the new hardware features, see the "New and Changed Information" section.
Determining the Software Version
To determine the version of Cisco IOS software running on your Cisco AS5300, log in to the Cisco AS5300 and enter the show version EXEC command:
router> show versionCisco Internetwork Operating System SoftwareIOS (tm) 12.1 Software c5300-i-mz, Version 12.1(5) XM8, RELEASE SOFTWAREUpgrading to a New Software Release
For general information about upgrading to a new software release, refer to Upgrading the Cisco IOS Software Release in Cisco Routers and Modems located at:
http://www.cisco.com/warp/public/130/upgrade_index.shtml
Microcode and Modem Code Software
Microcode software images are bundled with the system software image with the exception of the Channel Interface Processor (CIP) microcode (all system software images). Bundling eliminates the need to store separate microcode images. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface processor boards.
You could have received a later version of modem code than the one bundled with the Cisco IOS software. The modem code in Flash memory is mapped to the modems. Unless you fully understand how Cisco IOS software uses modem code, it is important to keep the factory configuration.
To obtain the latest Cisco IOS software release compatible with Cisco MICA portware, refer to the Cisco AS5x00 MICA 6-Port and 12-Port Modem Module Portware/Cisco IOS Software Compatibility Matrixes at http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/5300/sw_conf/sw_ports/compmat/mca12prt.htm.

The following new software features are supported by the Cisco AS5300 for Cisco IOS Release 12.1(5)XM1.
SIP Diversion Header Implementation for Redirecting Number (CSCdr72341)
The SIP Diversion Header Implementation for Redirecting Number feature provides support for a new SIP header field; Call Control (CC)-Diversion. The CC-Diversion header field enables the SIP gateway to pass call control redirecting information during the call setup. Call control redirection is the redirection of a call based on a subscriber service such as call forwarding. Call redirection information is information is typically used for Unified Messaging and voice mail services to identify the recipient of a message. Call control rediversion information can also be used to support applications such as automatic call distribution and enhanced telephony features such as Do Not Disturb and Caller ID.

SIP Gateway Support for Third Party Call Control (CSCdr32290)
This feature adds SDP changes for third party call control in SIP for click-to-dial, mid-call announcements, voice mail, and a timed conference bridge initiation.
For further details, please see SIP Gateway Support for Third Party Call Control at:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121rel/sipcfs/caribou.htm#xtocid33510
New Hardware Features in Cisco IOS Release 12.1(5)XM
There are no new hardware features in the Cisco AS5300 for Cisco IOS Release 12.1(5)XM2.
New Software Features in Cisco IOS Release 12.1(5)XM
The following new software features are supported by the Cisco AS5300 for Cisco IOS Release 12.1(5)XM2.
Enhancement to Fax Detection Feature for the Cisco AS5300
Users can now route fax calls to a fax e-mail address based on the redirecting dialed number (RDNIS), the dialed number (DNIS), or on a user-specified string, in addition to previously existing choices. RDNIS is the telephone number that is dialed for a particular subscriber before a call is transferred, on busy or no answer, to a shared voice/fax mail access and deposit number (DNIS).
A new keyword in the session target mailto: command ($m$)specifies use of RDNIS as part of the fax e-mail address if RDNIS is present; otherwise, DNIS is used. Additionally, a string can be entered, which allows the fax e-mail to be sent to an address that is not necessarily based on a telephone number.
Fax Detection for Cisco AS5300 Universal Access Servers
On Cisco AS5300 gateways equipped with voice feature cards (VFCs), the fax detection feature lets service providers deploy unified communication applications where each subscriber has a single E.164 number for both voice mail and fax mail. When configured for fax detection, the gateway automatically listens to incoming calls to discriminate between voice and fax. The gateway then routes the calls to the appropriate application or server.
Note
H.323 Call Redirection Enhancements
The user-to-user information element (UUIE) of the facility message is used primarily for call redirection. The UUIE contains a field, facilityReason, that indicates the nature of the redirection. The H.323 Call Redirection Enhancements feature adds support for two of the reasons: routeCallToGatekeeper and callForwarded. It also provides a nonstandard method for using the facility message to effect call transfer.
Route Call to Gatekeeper
There are two situations in which the Cisco H.323 Gateway might receive or generate a facility message with a routeCallToGatekeeper reason.
•
–
–
•
Upon receiving the message, the intermediate Cisco H.323 Gateway sends a facility message to the originator of the SETUP message. This message indicates that the SETUP message should be sent to another address. (The gateway includes the callSignalAddress from ARJ in the alternativeAddresss field of the facility message.)
Upon receiving the facility message, the calling gateway terminates the initial call and sends a new SETUP message to the specified gatekeeper, using the new IP address specified in the alternativeAddress field of the facility message. If the callSignalAddress is not provided, the gateway will not send the facility message and the call is terminated without any rerouting.
Call Forward
In certain cases, an H.323 endpoint might determine that a call needs to be forwarded. The endpoint then sends a facility message to the gateway with a facilityReason of callForwarded. This message includes the address of the new destination (either an alternativeAddress or alternativeAliasAddress).
Upon receiving the facility message, the Cisco H.323 Gateway sends a release complete to the original destination endpoint and initiates a new call using the new destination address supplied in the facility message. The release complete message contains a ReleaseCompleteReason of facilityCallDeflection. If the gateway is registered with a gatekeeper, the gateway sends a DRQ to the gatekeeper and waits for the DCF before sending a setup message to the destination gatekeeper.
The facility message must contain an E.164 address in the alternativeAliasAddress field. If no address is included, the facility message is ignored. The E164 is required because the call forwarding process initiates a new call, which may be subject to authentication processes that can handle only E.164 addresses.
If the facility message contains both and IP address (in the alternativeAddress field) and an E.164 address (in the alternativeAliasAddress field), the gateway first attempts to find a match for the new E.164 and the dial-peer. If there is no match, the gateway uses the same incoming peer to determine if there is a matching peer to reroute the call. If there is no match to the incoming peer, the message is ignored.
Call Transfer
If a facility message with a facilityReason of callForwarded is received after the call has been accepted, it is considered a call transfer. In this case, the Cisco H.323 Gateway will place the call on hold and initiate a new call using the address (alternativeAddress or alternativeAliasAddress) supplied in the facility message.
As with call forwarding, the facility message must contain an E.164 address in the alternativeAliasAddress field. If no address is included, the facility message is ignored. The E164 is required because the call forwarding process initiates a new call, which may be subject to authentication processes that can handle only E.164 addresses.
If the facility message contains both an IP address (in the alternativeAddress field) and an E.164 address (in the alternativeAliasAddress field), the gateway first attempts to find a match for the new E.164 and the dial-peer. If there is no match, the gateway uses the same incoming peer to determine if there is a matching peer to reroute the call. If there is no match to the incoming peer, the message is ignored.
Unlike in the call forwarding case, the facility message is accepted by both the called side and the originating side.

Media Gateway Control Protocol Basic CLASS and Operator Services
The Media Gateway Control Protocol (MGCP) Basic CLASS and Operator Services (BCOS) are a set of calling features, sometimes called "custom calling" features, that use MGCP to transmit voice, video, and data over the IP network. These features are usually found in circuit-based networks. MGCP BCOS brings them to the Cisco IOS gateways on packet-based networks.
The MGCP BCOS software is built on the MGCP CAS PBX and AAL2 software package, and supports MGCP 0.1 and the earlier protocol versions Simple Gateway Control Protocol (SGCP) 1.1 and 1.5.
The following two features can be run as trunking gateway (TGW) features:
•
This feature is supported in SGCP and MGCP modes on the Cisco AS5300.
•
This feature is supported on the G.711a and G.711u codecs only.

Open Caveats—Cisco IOS Release 12.1(5) XM2
This section documents possible unexpected behavior by Cisco IOS Release 12.1(5) XM2 and describes only severity 1 and 2 caveats and select severity 3 caveats.
•
When the PPP Password Authentication Protocol (PAP)-password validation fails—that is, when the PPP PAP password is configured incorrectly—a slow memory leak occurs. There is no workaround.
•
The CLI command isdn negotiate-bchan resend-setup does not show up when using the CLI help feature. This command allows Cisco IOS software to try a different B channel when a call setup on an initial B channel fails—for example, due to a Continuity Testing (COT) test failure. Turning on this option is recommended when using the isdn switch-type primary ni command in order to increase the call success rate.
Workaround: Configure the isdn negotiate-bchan resend-setup command, even though it is not yet documented as a command.
Resolved Caveats—Cisco IOS Release 12.1(5) XM2
All the caveats listed in this section are resolved in Cisco IOS Release 12.1(5) XM2. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
If a Class-3 switch that is connected to an ISDN PRI interface of a Cisco AS5300 initiates a call, the call uses a SIP proxy, reaches a gateway, and is terminated at another switch. Most of the calls are completed properly (that is, a tone is generated and the phone is answered), but randomly some of the calls do not complete and no error message is produced in the Cisco AS5300 log. There is no workaround.
This caveat is resolved in Cisco IOS Release 12.1(5)XM2.
•
Cisco IOS software contains a flaw that permits the successful prediction of TCP Initial Sequence Numbers.
This vulnerability is present in all released versions of Cisco IOS software running on Cisco routers and switches. It only affects the security of TCP connections that originate or terminate on the affected Cisco device itself; it does not apply to TCP traffic forwarded through the affected device in transit between two other hosts.
To remove the vulnerability, Cisco is offering free software upgrades for all affected platforms. The defect is described in DDTS record CSCds04747.
Workarounds are available that limit or deny successful exploitation of the vulnerability by filtering traffic containing forged IP source addresses at the perimeter of a network or directly on individual devices.
This notice will be posted at http://www.cisco.com/warp/public/707/ios-tcp-isn-random-pub.shtml.
This caveat is resolved in Cisco IOS Release 12.1(5) XM2.
