E911 Geolocation Service

You can register each IP-based phone with an emergency call service provider by supplying the E911 Geolocation information. Registration obtains the location of the analog phone that connects to the ATA. The location can specify the street address, building number, floor, room, and other office location information. When you dial an emergency number, the emergency service receives the phone location and a call-back number. If an emergency call disconnects, the emergency service uses the call-back number to reconnect to the caller.

To configure this feature, use the parameters under the E911 Geolocation Configuration section from Voice > Line (n) of the ATA administration web page.

You can initiate a problem report remotely. To do this, initiate a SIP-NOTIFY message from the server to the ATA, with the Event specified as prt-gen.

When the ATA receives the notification, it generates a PRT and sends it to the specified server when you set the parameter PRT Upload URL. The notification is in the form of a SIP message, and the PRT is transmitted over the HTTP and HTTPS protocol.

You can access a remotely-initiated problem report from the same location as locally-initiated problem reports on the administration web page.

This feature has no user impact.

Cisco ATA 191 and ATA 192 Analog Telephone Adapter Administration Guide for Multiplatform Firmware

This feature enables you to send call statistics to a remote end when a call terminates or is on hold. The statistics include Real-time Transport Protocol (RTP) packets sent or received, total bytes sent or received, total number of packets that are lost, delay jitter, round-trip delay, and call duration. Thus it helps the server to collect audio quality data.

• When a call terminates, the SIP BYE message appends headers such as RTP-RxStat, RTP-TxStat for audio session.

• The call statistics are sent as a new header in the BYE message or in the 200 OK message (response to BYE message).

• When a call is on hold, headers RTP-RxStat, RTP-TxStat are sent in the Re-Invite SIP message.

• When a call is put on hold, in the 200OK for this Re-Invite headers RTP-RxStat, RTP-TxStat are sent.

New Log Modules Support for Audio Issues

You can enable the debug logging for the audio related issues. After you enable the audio debug logging, you can track what happened and troubleshoot audio related issues according to Real-time Transport Protocol (RTP), facsimile (Fax), and the voice related messages.

To enable the specific log modules, use the CSSD_RTP, CSSD_FAX, or CSSD_ANY fields from the Administrator > Log > Debug Log Module page.
