Re: [cisco-voip] Force an outgoing call through a subscriber

[Ryan Huff]

Anthony,

Yes, it is splitting hairs IMO :). I'm specifically talking about a typical 
scenario where RTP is sent from/to the phone for a connected, like-codec call 
that is not forcing media termination with the next device in the call leg.

As you and I have mentioned, there are a handful of ways to use different 
features and services of a CUCM server to terminate and join media streams 
(MTP, CFB ... etc) ... and I considers these as ancillary service and component 
capabilities to the server and not a core function of the server itself (hence, 
media not flowing through the server, although it maybe interacting with one or 
more of the aforementioned media services or components).

Always happy to split hairs :).

1) Your first sentence reads to me like a contradiction.  Could you clarify 
what you're stating here?

2) Media can flow through, and even terminate on CUCM, since things like 
Conference Bridges, MTPs and now the new IVR media resource, are all doing that.

If you see a CUCM IP address in the Audio field of the SDP, then it's likely 
terminating on a CUCM based MTP resource (most often, due to some differences 
in DTMF negotiations or because the egress path in CUCM is required to use MTP).

If you are trying to test a call using a CUCM MTP resource on a particular 
cluster node; the simplest way would be to create a new MRG/MRGL that only 
specifies MTP resources from the desired cluster node and then advertise that 
MRGL to the phone and/or egress path to the pstn for the phone and then 
"require" MTP termination from the phone or egress path.

Is the problem you're troubleshooting have anything to do with one-way or 
no-way audio by chance?

Thanks,

Ryan

Hi, Guys.

I need to test problems with calls outgoing from an Ip phone to the PSTN  
through a particular subscriber (as MTP?).

How can I force them to do that.

Packet captures show me that, at times, calls go from my phone to the h323 
gateway and sometimes they go from my phone to the Sub and then to the gew.
