SRST config problems

Jakub Stroinski
Level 4
Level 4

I'm trying to configure SRST on our gateway when CUCM goes down.

Our auto attendant is on DN 2000 in CUCM (goes to UCCX)

Our sample phones are 2001, 2339, 2340, 2810, 2820

2001 is a SIP 7821 while the others are SCCP phones

When the WAN is up, all phones ring instead of being answered by the auto attendant and are registered with CUCM.

When the WAN goes down, all phones ring as expected and are registered in SRST with the gateway.

In addition, when a call is answered on the SIP phone through SRST, no audio is heard. When a call is answered on the SCCP phone, there is audio.

 

I have tried using the alias command in call-manager-fallback; I set alias 1 2000 to 1999 and changed my hunt pilot to 1999 but that didn't work at all. If I set alias 1 2000 to 2339, my phone rings but not in the manner that I wish

 

I've pasted my config below. Any advice would be incredibly helpful

If you want enhanced routing capabilities, you probably want to look into CME-as-SRST instead of plain SRST.

if this helps, please rate

Im looking at this

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/admin/configuration/guide/cmeadm/cmesrst.html

 

Everything is for SCCP phones it seems. Is there an equivalent for SIP?

Hi,

 

I am not sure if I understand your requirement. If your question whether SIP supports SRST, the answer is yes.

 

Also, SIP SRST support hunt groups but as Jamie mentioned, you need CME-SRST instead of traditional SRST

Bringing this back from the dead

Under normal circumstances, when a call comes in on our gateway it is sent to 2000 which is a CTI port for UCCX

When we're in SRST mode, I would like all calls to go to extension 2339 on a SIP phone

If I modify my translation profile in my GW to point to 2339, it works. How would I go about having it automatically change to 2339 from 2000 when we fall to SRST mode?
