Hi Allwyn,

If you're troubleshooting basic call routing/dial-peer matching you will probably want to run a 'debug voip dial-peer'.  If you're looking for more detailed information including Q.850 disconnect cause codes 'debug voip ccapi inout' is a good one as well.  However, a lot of the debugs that you may be looking for will depend on what protocols and signaling types are running.  Ex. 'debug isdn q931' is great for T1 PRI's, etc.  Your exact call-flow is also required to define which debugs would be required to track calls going in and out of your system.

Hi Chris,

The call flow is like a PSTN user is dialing one bridge number which is actually a Microsoft Lync bridge.How we have setup

is the PSTN call will come to our Router where CMEis running and it will go to Lync through SIP Trunk.

We want to trace this incoming call..Hope this info will help you...

Hi Allwyn,

How are you connected to the PSTN?  If it's a T1 PRI and you want to trace the inbound and outbound call leg to the PSTN, then a 'debug isdn q931' would give you the inbound and outbound layer 3 information of all calls to and from the PSTN. 

HTH,
