Remote Callers can't hear ringback on E1

Gustavo Adolfo Villanueva Ramirez · ‎04-08-2014

I'm running CMExpress on Cisco 2911 with one E1 card and callers can't hear ringback when the call is actually ringing in the local site. They just hear one ringback on the establish of call and after that, nothing until the end-user off-hook the phone.

Can someone have an idea about this issue?

Hi Tavo,

Can you try adding a line to your VOIP dial peer:-

Something like:-

!
!
dial-peer voice 2000 voip
desc *** VOIP DP TO CUCM SUB ***
destination-pattern 2...
session target ipv4:172.16.255.22
codec g711ulaw
progress_ind setup enable 3
!
!

Hope this helps

Hi Alex, your comment make me update my case, i'm actually runnning CME with SCCP and SIP phones registered on it and when i called to any of this extensions, anyone made ringback tone.

Thanks for your help.

Tavo,

What version of CME are you running and what is the router IOS version ?

You may be hitting bug CSCdw73507 if it is old ios 12.2 etc

Does the issue happen with both the sip & sccp phones ?

This my CME and IOS version:

=====================
Version 9.1
Max phoneload sccp version 17
Max dspfarm sccp version 18
Cisco Unified Communications Manager Express

======================

Cisco IOS Software, C2900 Software (C2900-UNIVERSALK9-M), Version 15.2(4)M4, RELEASE SOFTWARE (fc2)

=======================

The issue is similar to the bug CSCdw73507, When a call come from PSTN, the Caller just hear one ringback, but my IP Phone rings normal.

This is my Incoming Dial-Peer

dial-peer voice 7 pots
description ### INCOMING CALLS E1-PSTN ###
translation-profile incoming To-AA
incoming called-number .
direct-inward-dial

Thanks in advance for your help.

Alex,

I already added these commands, but this issue continues, Do you think my E1 Provider has some work to do about it?

Thanks in advanced for your help.

Tavo.

Caller who calls a DID don't hear ringback, but when a AA is playing and Caller Dial an Extension in that moment he can hear ringback.

Call -> DID -> CME -> AA (Unity) -> Dial Extension -> Ringback (YES)

Call -> DID -> CME -> Ringback (NO)

Hi,

The problem is resolved using this two commands just in POTS Dial-peer :

progress_ind setup enable 3
progress_ind alert enable 8

Could you try those commands

Aaziz

Aaziz,

IOS mark as Invalid input when i tried to use these commnds on POTS Dial-peer, but in VOIP (NO MY CASE) I can use them.

Thanks for your help.
