Hello to everyone,
I have recently installed a UCM 6202 to a customer. The system has 1 analog Trunk (FXO) and one VoIP trunk (SIP Trunk). Inbound and outbound rules work perfectly except that the customer wants
see the original caller id if the call is forwarded to his mobile phone.
The exact opposite of this topic :
# Change in Caller ID Behavior between Firmware versions and hardware
The situation is that i cannot make this to work regardless of what i did inclouding changing the Keep Original CID option in the SIP Trunk options. You see the main incoming number is the PSTN line because that is the number all his customer know but the forwarding to his mobile phone is done via the SIP Trunk because the rates to mobile phones of the SIP Trunk is much cheaper.
Can you provide some assistance??
Thank you in advance
