Unsupported Grandstream UCM 6204 - Caller ID

[Vineeth Mohan]

Hi,

I have UCM 6204 on which I had terminated the SIP trunk. Everything seems to work fine but I am not able to pass the original caller ID to 3cx. What I see on 3cx is the Caller ID I had set up.
Can anyway please help me in passing the original caller id which will help me generate the reports.

Thanks in advance
