Region : Switzerland

Model : TD-W8968

Hardware Version : V1

Firmware Version : 0.6.0 1.0 v0001.0 Build 130413 Rel.52459n

ISP : Sunrise

I have set up the TD-VG3631 with the ISP Sunrise here in Switzerland.

The voice function works well outbound over SIP accounts.
But when calls are coming inbound over PSTN, the CLIP (Caller ID) does show 0.

There is a Panasonic DECT KX-TG6621SL at Port 2 connected.

Is there any possibility to adjust the CLIP / Caller ID settings?

Thank you.
