Caller ID not showing on incoming calls on ISDN E1 - CUCM

[layhlaing]

Hi,

I am not getting caller ID on incoming calls via ISDN E1 line. We have ISDN E1 --> 2901 E1 --> SIP --> main CUCM.

Following is the output of debug voip ccapi inout:

Could anyone please share some knowledge on where I should double check for this? Incoming calls are showing as "Unknown Number" on phones. Attached is the extract of voice configuration from the site voice router. I have enabled/checked "Media Termination Point Required" on the site's SIP trunk in our main CUCM. Please let me know if required any other info.

Thank you and regards,

Lay

Check "debug isdn q931" with "term mon" to see if telco is sending calling number.

If they don't, complain to them.

Thanks very much for the prompt advice. Sorry, I missed to mention that calling party number was not seen in debug isdn q931 output.

As seen in above, None is seen in Codec until call is picked up. However, I can see g711ulaw once the call is picked up.

I should also mention that we have migrated from old Nortel PABX with this "ISDN E1 --> 2901 E1 --> SIP --> main CUCM" using the existing ISDN E1. Caller IDs were shown on the old system (however it was ISP-managed system who is also the provider of E1) and I wonder if it is me wrong in somewhere in the configuration. Could you please advise if there is any other possible thing I should check?

Thanks again.

No, there is nothing else you can do on your side, you have to ask telco to send calling number.

Thank you for the nice rating and good luck!

Hi Paolo,

You are right about this, I have raised a call with telco and they have confirmed that CLI was not enabled on the trunk. And the calling number can been seen on the incoming calls. Thanks very much for your help.

Cheers,

Lay
