Cisco to Nortel QSIG - No ringback

[angel-moon]

Hello everyone,

on a Cisco to Nortel PRI QSIG trunk calls complete as the should and on Cisco to Nortel calls we get ringback as we have the command  progress_ind alert enable 8 in the dial-peer sending calls over the QSIG to Nortel.    I have the same command, progress_ind alert enable 8 in the dial peers sending the calls from the Nortel to Cisco but Nortel callers are not hearing ringback.  Any clues as to why the Nortel callers are not hearing ringback?  My suspicion is that the issue lies with the Nortel side but want to make sure.         

Thanks in advance. All replies rated.

Hi,

I am assuming that the Cisco side is CUCM,

Can you try this:-

Service Parameters

from the Cisco CallManager Administration page.

Choose the Publisher CallManager Server and Cisco CallManager service.

Advanced

Scroll down to Disable Alerting Progress Indicator from the Clusterwide Parameters (Device - PRI and MGCP Gateway) section. Set this parameter to False and click Update.

Save

Test

Regards,
Alex.
