SIP Notify

Unanswered Question
Sep 21st, 2007

Hi, i have a AS5300 and want to configure a sip notify in a voip dial-peer. but somehow the sip-notify is not available. I have read some info in the IOS and it is available 12.2(15)ZJ but unfortunately that IOS was on a DF released. And my current IOS is c5300-js-mz.123-23, which i supposed it is already available, but its not. Can someone guide me or assist me on which IOS do I need to configure an SIP Notify.. Thanks in advance

I have this problem too.

To use voice mail on a SIP network that connects to a Cisco Unity Express system, use a nonstandard SIP Notify format. To configure the Notify format, use the sip-notify keyword with the dtmf-relay command. Using the sip-notify keyword may be required for backward compatibility with Cisco SRST Versions 3.0 and 3.1.


1. dial-peer voice tag voip

2. dtmf-relay sip-notify

3. exit

4. sip-ua

5. notify telephone-event max-duration time

6. exit

Here is a link that talks about IOS releases needed to support the SIP DTMF features:

The As5300 is a fairly old platform and is not supported in the 12.3T train (which is where 12.2(15)ZJ rolls into) hence you do not have the option. You need to move to an AS5350XM or AS5400XM which has this support.
