Additional SIP Services

Dial Plan

You can set specific dial plan rules and timeout values. Many of these values are determined on a country-by-country basis.

DialPlan, page 5-38

Disabling Access To The Web Interface

To prevent tampering and unauthorized access to the Cisco ATA configuration, the Cisco ATA built-in web server can be disabled.

Distinctive Ringing

This feature allows a user to identify a caller based on the ringing pattern the user selects for the incoming number.

This feature is dependent on the proxy or remote UA, including the Alert-Info header with the appropriate value in the INVITE message. The Cisco ATA supports standard distinctive ringing pattern

1to 5 as defined in the standard GR-506-CORE. The following Alert-Info header values are allowed:

•Bellcore-dr1

•Bellcore-dr2

•Bellcore-dr3

•Bellcore-dr4

•Bellcore-dr5

If the Alert-Info header value is not recognized, the Cisco ATA plays the regular ring tone, Bellcore-dr1.

Note The Bellcore-dr5 ringing pattern is the same as the Bellcore-dr1 ringing pattern.

DNS SRV Support

The Cisco ATA supports DNS SRV lookup for the SIP proxy server. If the GkOrProxy parameter value begins with _sip._udp. or sip.udp., the Cisco ATA performs a DNS SRV lookup for the SIP proxy server. A DNS SRV lookup results in one of the following conditions:

•Zero host is returned or DNS SRV lookup failed. The Cisco ATA then performs a regular DNS A-record lookup for the given name.

•One host is returned. The single host is used as the primary proxy and AltGk is the backup proxy, if specified.
