View Full Version : Unknown Caller ID

07-27-11, 10:34 AM

I have an issue when i received calls from my pbx using e1 line connected via FXO port.

When i received calls from GSM line or land line, it shows unknown number on the screen of my Aastra 57i Ip-phone.

What can i do to resolve this.

First I would suggest confirming there is caller id available on your FXO line if you already have not. For example, if you plug an analog phone into the FXO line is there caller id present?

What country are you located? Do you know what type of caller id might be present on the line? For example, FSK or DTMF? In the file '/etc/pika/pikagp_aoh.cfg' you will find a 'calleridmode' field. This can be set to match the callerid present on the line.
