Problem on ISDN - 2*BRI. Call does not setup properly

Yannick Vranckx · ‎01-27-2014

Dear All,

We are having some issues on a fresh installation with a Cisco 2911 connected to a remote Call Manager in Denmark. The branch site is in Belgium, when we connect the BRI's to the interfaces we get a "multiple frame established" so all is well there.

When i start a call to the outside ( mobile number), my cell phone receives it but there is no voice, when i speak through the phone my cell phone only hears static noise and after 8 seconds the call is hang up.

I've tried playing with the codecs but no luck, we should be sending the usual G711alaw. Although when i go adjust in Call Manager and make the Gateway "Media Termination Point Required" , enable Outbound FastStart with G711alaw there is 2 way voice for about 12 seconds, after this the call is ended aswell.

With no adjustsments in call manager i get the following error code:

Cause i = 0x80AF - Resource unavailable, unspecified

With adjustments in call manager: MTP, outbound faststart, i get the following:

Cause i = 0x80A9 - Temporary failure

I've done some debugging on the gateway:

************************************Call To Mobile Phone, call is received but no voice on the line, just static noise every time i talk**************

I see that they have the compressed codec, is this correct? Shouldn't that be G711?

Hermanus Janse van Vuuren · ‎01-27-2014

Yes it needs to be G711.

You can work thru this as well.

Ok,

Can u walk me through how i configure the DSP's with the G711 codec, I have already set up a transcoder and MTP and CFB and they are all registered in Call Manager.

What does your incoming and outgoing dial peers look like?

The codec of the DSP is still on G729r8, i have disabled the transcoder to see if that works but that didn't work either.

My dial-peers look like this:

Yannick Vranckx · ‎01-28-2014

In the meanwhile i fixed this issue with using a different protocol to register the voicegateway to callmanager.

Instead of H.323 i am using MGCP now, it looks ok now.

Just have one more question, where can i do the number translations to add the zeros on the display so a redial can work.

Thanks Guys for the assistance

Hermanus Janse van Vuuren · ‎01-28-2014

Either on the route pattern or you can do a Route List and make add a zero there.
