Actually I have a Nokia22 designed to be connect to PBX extension system. That device has two analog interfaces: trunk and extension. I have tested with succesful results the Nokia 22 connect to a PBX extension. Doing the following steps:
* User dial mobile extension.
* Receive a dial tone.
* Dial code that allow user on PBX telephone dial again.
* Mobile gets digits and establish the call.
These is the normal proceeding but, it do not work on a callamanger system.

The problem.
* User dial mobile extension (Mobile connected to ATA port).
* Receive a dial tone.
* Can dial digits but mobile seem not to recognize digits.
How can I do that. Has someone been involved on that problem?
Thanks,
Sergi.
