First of all I apologise if this is something simple (and already discussed) problem, I may just not know the correct terminology.
I have an asterisk setup and need to allow users to be able to register with a username and password but have the caller ID different from their username. Mainly so they could send different caller ID’s for billing purposes through the same authentication.
When I change the caller ID on the SIP client at the moment, I have done a trace and it appears to change the URI(?). It will then not register with asterisk.
I hope this makes sense, any help is greatly appreciated.
