SIP Trunk in CUCM

[niterid3r]

Hi,

We are running CUCM 8.5 on which i created a SIP trunk to Avaya CM 6.0

Just wondering what tools to use in CUCM to check if the SIP trunk is up and running.

At this point when i dial a number destined to that trunk is having a busy tone.

Any help would be appreciated.

Thanks.

Hi, You can use Session Trace feature in RTMT to check the SIP call logs.

could you please collect the CCM SDI traces (Level-Detailed) for a test call and provide the info like, calling number, called number & time of call?

are the calls from Avaya to CUCM working?

In this forum at the top is a link to a new tool to help in looking at SIP debug traces in callmanager - may just help a lot.

This is what i get in the call flow, It looks like the connection is up but the number i am dialing is not found on the far end. Please correct me if my understanding is incorrect. Also i am not sure what does error 403 Forbidden means.

Hi,

Generally '404 Not Found' means the called number sent to the far end HO-Avaya is in incorrect format or not configured in far end. It is dial-plan issue.

'403 Forbidden' indicates that the IP address in the Invite message sent to EPCC-Avaya is in incorrect format and hence it is rejecting the call with 403 error.

Hope it helps.
