[SR-Users] Add CallerID to SIP header

[Dominic Raferd]

I'm not yet using Kamailio. I am looking for something to do a job which 
sounds really simple but may not be. Our PBX connects to a SIP service 
(voicetrading.com) but does not supply our CallerID, this means that 
voicetrading.com provide some very weird callerids for the person at the 
other end (international numbers etc). Which is not good.

There is no way to get our PBX to add CallerID itself, so I thought 
maybe I could set up a local sip proxy? or sip redirect? server 
(Kamailio?) to do nothing other than add in the callerid details to the 
sip header and then forward the sip message on to voicetrading i.e. be 
otherwise 'invisible'?

If Kamailio is not the right thing to do this with, is there something 
else that could do it?

Thanks for any suggestions.
