Sending Caller ID from PSTN to IP Phone.

[peternnaji]

I tried calling an IP phone with a PSTN number but it does not go through. Can anyone be of help please.

Is the caller-id service present and working on the line ?

Is the voice-port configured for caller-id and correct cptone ?

Hi bevilacqua

Yes the cptone is correct, but not so sure of the voice-port config for caller-id. an you help out?

First of all you have to test the service by connecting a regular phone with caller id to the line, and verify that you can receive caller id.

Then for configuration, under voice-port just configure "caller-id enable".

If caller id doesn't work, please send configuration and output of "term mon" and "debug vpm signal" when receiving a call.

Hope this helps, please rate post if it does!

Hi,

I tried the config for "caller-id enable" under voice port but it doesn't accept it. Attached is the router config.

Hi,

You have no analog voice port so there is no need to configure caller-id. Please look at the output of "term mon" and "debug isdn q931" to observe which calling number is being sent from telco.

Note: these commands that you have configured:

voice call send-alert

voice call convert-discpi-to-prog always

voice rtp send-recv

voice disc-pi-incoming-on

Unless you have a reason to have them, are unnecessary and can be cause of trouble.
