I have 2 GSM gateways - 1600 and 2120 series. Software version is 2.1.3.
Incoming calls from GSM translates to sip account.
I'd like to ask: is it possible to change callerid name with saving original number.
What i mean: if original caller's number is +1234567890 by default gateway copy it to calleridname. When I set callerid name to 'SIM1' in call routing rule, i get CallerID equals to 'SIM1'.
So is it possible to change callerid name to something like 123457890 (SIM1)?
So, much thanks to crystal.han, my issue was solved.
The resolution is: you need to paste expression like ${CALLERID(num)}(SIM1) into "Set the CallerID name to" field of call routing rule. After that callereid transferred to SIP enpoint looked just like I wanted:
1234567890(SIM1)
That's bad. Because of that I'll have to add a call routing rule for each port. I need to identify on which port call comes to, If this will become possible, that would be great.
