Hi all,

I am sure I am missing something, which most of the time end up being obvious.

The problem is that I am trying to configure an Atcom's IP-BRIM device to work with our ISDN lines, using IAX2.


Although we manage to make it work fairly successfully so far, as we are able to make and receive calls, we are suffering with a few problems that I list as follows:


- Whenever we make or receive an external call, we have trouble hearing the other side of the line. It's like their voice is sinthertized with a few clicks and pop at regular intervals. However, the other side can hear us perfectly. Also, when we call another internal extension, the call quality is perfect.

- I am not able to group pickup using *8 or direct pickup using **{Extension}.

- Whenever we receive a call, we don't see the caller number (Caller ID) on the phone screen. It shows "Unknown" instead. But I can telll the telco is sending the caller ID because when the call terminates, if I press the "LOR" soft button, the number of the caller will show up so I can return the call.


I wonder if anybody was able to setup an IP-BRIM or similar and perhaps is familiar with the above problems and could give a few clues about what we should try net.

Many thanks in advance and kind regards,
Joe

solution: switch to SIP. Now everything works. My only guess is that IAX2 is not correctly implemented on the above combination.
