Hello to All I have been trialling a SBC for my VoIP solution but the problem I have is that the SBC needs to have an entry in the sip.conf inorder for the asterisk to accept registration requests from the SBC. This is ok if I only have one company registering as the entry in sip.conf for the SBC needs to have a context specified therefore I cannot have different companies registering through the SBC as they will all end up hitting the asterisk and being seen as the same context. When I had users register direct to the asterisk there would be an entry for each user in the sip.conf which would tell asterisk which context that paritcular user/extension was in so I could then have different extensions, services etc on a per company basis. Does anyone use another SBC piece of hardware or have another solution for SBC or have any idea on how I can over come the issue above. I hope I have explained it well enough, if not please do not hesitate to fire some questions at me. Many Thanks Scott Pinhorne
