SIP calls through CUCM 8.6.2 ring and when answered fast busy

somersettrust
Level 1
Level 1

We are testing SIP through one of our offices and are having trouble with the calls going through. When we place the calls they ring like a normal call, but when answered you get a fast busy. We have SIP service provided through Level 3 communications. I spoke with them for debug purposes and they're seeing the call ring acknowledged, an ok when answered and then an immediate bye. I'm not sure if it's a config issue in Call Manager or on the gateway.

 

here is the  level 3 debug, they provided me:

Here's a call debug, that I just produced:

Hi somersettrust,

Can you paste your CUBE configuration here?

Level 3 Communications provides our SIP service and manages the CUBE on their side, so I don't have the config. I worked with one of their engineers, trying to troubleshoot the problem and seem to think it's coming from my voice gateway or CUCM. I can provide you with info from my voice gateway or my call mgr. When I place the call, it rings to the called party, but once it's answered the call goes fast busy. I set a route pattern up, for my cell phone, for testing purposes. I originally discovered the problem trying to test 911.

Yes, running-config from your VGW would be helpful.

here's the vg config: We have approximately 25 offices running through 2 PRI's. we just implemented SIP for a new office.

You should have a region for your Branch office, and a region for your SIP trunk between CUCM and your GW.  <- Very important. 

 

Your current call flow: 

IP phone --- sccp to ---> CUCM ---SIP trunk to -->CUBE gateway ---SIP Trunk to ITSP--> .

 

To test make sure you have your Iphone in X_REGION and your CUCM sip trunk in Y_Region. Then make sure your region relationship between X and Y = 64 kbps. Then test. 

 

Also....

The Cube config has a voice class with g711ulaw and g729r8 allowed to the ITSP. But your transcoder profile does not have g729r8 in it. I suspect if your region  is negotiating g.729 between iphone and CUCM-CUBE sip trunk, it won't be able to transcode to g711ullaw to leave to the ITSP.

 

Let me know.

I'm making the changes now, but won't be able to test it until tomorrow morning. As soon as I test it, I will let you know.

Thanks for the advice.

Glad it worked! The CUBE has to have a 911 voip dial peer with the voice class specified. 

 

On another note, your calls were not going through because transcoding is not setup properly on your CUBE. What was happening was your IPphone was negotiating G.729 all the way to the CUBE, but the the CUBE negotiated G.711 to the ITSP. So when the call connected, your CUCM noticed the mismatch and disconnected by sending the "bye" sip message. This can be fixed if your CUBE is properly setup for transcoding, because using G.711 all the time will consume more bandwidth, and you always want to have both codecs working anyways.

 

Please make sure your SIP Trunk's MGRL in call manager is in the same region as your SIP trunk, and then fix the config on the CUBE. You need to include G.729r8 under the profile for transcoding.

 

Good luck and rate useful! 

I have 911 working. When I would call it, it would say "call can not be completed as dialed". I created a new dial-peer specifically for 911 and that fixed it.

I will verify the SIP Trunk's MGRL relation to the Region. I will also check the config for the transcoding.

 

Thanks again

I added the Region and tweaked a few other settings and the calls went through. Thanks!

I'm still having an issue calling 911, but I haven't looked at the dial peers in the VG. I suspect that may be the problem.

I had this issue once, it turned out to be a codec mismatch. One side supported G.711 only while the other side was negotiating  G.729 and the transcoders were not setup properly. I initially created a separate voice class in the CUBE to force G.711 and that's how I figured out what was wrong.

Make sure your call manager regions' relationships are setup properly.

 

Thanks,

 

 

I tried modifying the region, of the office that we are testing SIP in and that didn't work. Do I need to modify the codec for the new office in relation to all the other offices (we have 20 plus offices) or just the main office (containing the VG and CUCM)?
