I am running CUCM 9.0 with cisco voice gateway. All internal extensions are able to call PSTN and vise verse. The issue happens when a call is dialed from PSTN that is forwarded to Call Center queue. The phone rings but no audio is coming on both sides.
If I dial the queue number internally from an extension, it gives me welcome message and then routes to an available agent. But when I dial 8 digit number from PSTN, which is translated to internal queue extension, I hear the welcome message but after that when the call is forwarded to an available agent, the phone rings but cant hear each other.
I want to know why one thing works locally and does not when it is initiated from PSTN?
I would check if an MTP is being invoked somewhere that the gateway cant ping, maybe for recording or some other purposes. show sccp conn should tell you if its on the router. Else show call active voice summary should show IP addresses where the media is being sent.
Guys, I tried to route incoming call to another CUCM whivh is running on another site and that has a route pattern to my existing CUCM Queue extension. That worked absolutely fine. I can hear the sound without any issue.
I will tell you the call flow
In wanted scenario: Incoming call goes to Cisco voip gateway, that translates to 314 extension which is call center queue. The call is routed to the CUCM where 314 queue is configured.. but no audio...
In Test scenario: Incoming call goes to Cisco voip gateway, that translates to 314 extension which is call center queue. The call is routed to another CUCM running at other site, that has a route pattern of 3.. pointing to the existing CUCM where 314 queue is configured.. This works absolutley fine without any issue. We can hear sound on both sides... Both CUCM has SIP trunk to eachother..
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
