Help with Voice Gateway Outgoing Calls

umamon · ‎11-30-2009

Please Help. I have an analog line plugged into a fxo port for our backup just in our VOIP environment. I can make incoming calls to the analog line and it correctly forwards to the internal extension assign on the connection plar. But when i try and make a call from the router. I receive a disconnect. csim start has been pretty helpful in testing my other 28 sites.

error:

csim start 94231294
csim: called number = 94231294, loop count = 1 ping count = 0

csim err csimDisconnected recvd DISC cid(54)
csim: loop = 1, failed = 1
csim: call attempted = 1, setup failed = 1, tone failed = 0

Here's my configs:

Did u tried calling with IP Phones or with testing with csim only? Did u configured proper route patterns at CUCM?

I can see it's your MGCP gateway but didn't configured the voice-ports and dial-peers correctly according to MGCP configurations, you can have a look here for MGCP configurations:

Yes I only tried testing using CSIM... I very new to the voice side. I will read over the document you sent in the link. And let you know. Thanks!

too many unknowns for a definitive answer here

-

You are running CCM? What version (just for kicks and giggles)?

you have bits of MGCP and H323 - what do you want to run here?

You are catching the incoming calls with H323 dial-peers

Have you connected a buttset or normal analog phone to the FXO to check dial out? Some CO trunks do not provide dial-tone ( a human oriented signalling method) - you can still diall out as long as there is battery

Can you do a debug voice dialpeer to see which dialpeer you are matching outbound?

Also try a debug vpm signaling to see what is actually happening

Dial-peers 9000 and 9001 are also competeing with 100 and 101 - what are you trying to accomplish?

When you attempt to make a call "from the router" is only via CSIM?

Hello,

Sorry for little information. I am very new to the voice side of the router configs. I really don't have a lot of answers for you because I didn't configure the voice stuff, so I don't what the purposes of some of the features that is in the config. I only tested using CSIM. I will do some of the debug option you listed. Thanks!
