OutBoundProxy

Description

The SIP Outbound Proxy Server is a SIP proxy server which can be different from the Registration Proxy Server (specified in the GkOrProxy parameter) and to which all outgoing SIP requests are sent. Outgoing SIP responses are not affected by this out-bound-proxy and are still sent according to the VIA header and source address of the incoming SIP requests.

If the outgoing SIP request has a ROUTE header, the first route in the header is removed if it resolves to the same IP address as the out-bound-proxy. This process guards against the case when the out-bound-proxy also inserts its IP address into the RECORD-ROUTE header.

The OutBoundProxy parameter can be an IP address with or without a port parameter, such as 123.123.110.45, 123.123.110.45.5060, or 123.123.110.45:5061, or a URL such as sip.cisco.com, sip.ata.cisco.com:5061. For IP addresses, a period (.) or colon (:) can be used to delimit a port parameter. For a URL, a colon (:) must be used to indicate a port.

Table 5-4 ConnectMode Parameter Bit Definitions

Bit Number

Definition

0—H.323 only

0—Enable normal start.

1—Enable fast start.

1—H.323 only

0/1—Disable/enable h245 tunneling.

0—Use the dynamic payload type 126/127 as the RTP payload type (fax pass-through mode) for G.711 µ-law/G.711 A-law.

1—Use the standard payload type 0/8 as the RTP payload type (fax pass-through mode) for G.711 µ-law/G.711 A-law.

3—H.323 only

0/1—Disable/enable the requirement for the alternate gatekeeper to register.

4—H.323 only

0—Denotes a non-Cisco CallManager environment.

1—Enable the Cisco ATA to operate in a Cisco CallManager environment.

5—H.323 only

0/1—Enable/disable two-way cut-through of voice path before receiving CONNECT message.

6—H.323 only

0/1—Disable/enable using the Progress Indicator to determine if ringback is supplied by the far end with RTP.

0/1—Disable/enable fax pass-through redundancy.

8-12

Specifies the fax pass-through NSE payload type. The value is the offset to the NSE payload base number of 96. The valid range is 0-23; the default is 4.

For example, if the offset is 4, the NSE payload type is 100.

0—Use G.711µ-law for fax pass-through codec.

1—Use G.711A-law for fax pass-through codec.

14-15

0—Use fax pass-through.

1—Use codec negotiation in sending fax.

2—Reserved.

3—Reserved.

16—SIP only

0/1—Disable/enable SIP to remove the registration before adding a new one.

17—SIP only

0/1—Disable/enable call forwarding performed by the Cisco ATA. In SIP, call forwarding can be performed locally by the Cisco ATA or it can be performed by the SIP proxy. If this bit is disabled, the Cisco ATA forwards the entire dial string, including service activation code, to the SIP proxy for processing.

18—SIP only

0/1—Disable/enable SIP call return performed by the Cisco ATA.

0/1—Disable/enable the Cisco ATA to send a ringback tone to the caller.

20—SIP only

0/1—Disable/enable SIP to perform action=proxy in a REGISTER message.

21—SIP only

0/1—Disable/enable SIP to perform action=redirect in a REGISTER message.

22—SIP only

0/1—Disable/enable SIP to process a received= tag in the VIA header to extract the exernal IP addresses used by the Network Address Translation (NAT) router.

When the Cisco ATA is operating behind a NAT, the NATIP parameter must be set to the external IP address of the NAT router. This allows the correct IP address to be placed in the Contact and SDP headers.

In release 2.14 or later, you may leave the NAT IP address at the default value of "0" or "0.0.0.0" and let the ATA automatically scan the Via header for a "received=" parameter. The parameter, if present, would indicate that the Cisco ATA is operating behind a firewall.

The Cisco ATA proceeds as follows:

1. If the "received=" parameter is in an INVITE response, the current INVITE is canceled and a new INVITE is sent with the new IP address extracted from the "received=<NAT IP address>" parameter in the Contact and SDP headers.

In addition, the Cisco ATA will cancel all previous registrations and re-register with the new IP address in the Contact header. This step is performed only if registration is currently in an idle state.

2. If the "received=" parameter is in a REGISTER response as a result of a REGISTER command, the Cisco ATA will cancel all previous registrations and re-register with the new IP address extracted from the "received=<NAT IP address>" parameter in the Contact header.

Note For the Cisco ATA to automatically detect its presence behind a NAT, the SIP proxy server or remote user agent server must include the "received=" parameter in the Via header in the responses to the Cisco ATA if the proxy detects that the source address and port do not match those in the Via header.

0/1—Disable/enable the end user to specify the default call waiting state for every call. This can be done on a permanent basis.

0/1—Disable/enable the mixing of audio and call waiting tone during a call.

25—SIP only

0/1—Disable/enable DNS lookup of hostname "From" header hostname for call return.

26 to 31

Reserved.

Note You cannot simultaneously set bits 20 and 21 to 1. Also, if you set both these bits 0, the action parameter is not included in the REGISTER message, forcing the proxy server to perform the next step in the call process.

AutMethod

Description

This parameter is not used for SIP.

TimeZone

Description

This parameter is the timezone offset from Greenwich Mean Time (GMT) for time-stamping incoming calls with local time (to use for Caller ID display, for example).

Local time is generated by the following formula:

Local Time=GMT + TimeZone, if TimeZone <= 12
Local Time=GMT + TimeZone - 25, if TimeZone > 12

Value Type

Integer

NTPIP

Description

This parameter is the NTP IP address, required if DHCP server does not provide one.

The Cisco ATA requires an NTP Server from which to obtain Coordinated Universal Time (UTC) to time-stamp incoming calls (H.323 and SIP) to drive an external Caller-ID device.

DHCP may also supply a NTP server. If NTPIP is specified, it overwrites the value supplied by DHCP. NTPIP is ignored if its value is 0 or 0.0.0.0.

The user must not specify a port parameter. The Cisco ATA uses the default NTP port only.

Value Type

AltNTPIP

Description

This parameter is the alternate NTP IP address, if you want redundancy. You can set this parameter to 0 or point to the same NTPIP if only one NTP server exists.
