[Asterisk-Users] registering ALL ser users

[Iqbal]

Hi

I have setup sip.conf and extensions to accept and route calls to
voicemail from SER, but I have a strange problem, if the user in xlite
has username iqbal, then asterisk needs to have such a user in sip.conf,
which in turn would mean that all my users would need in there. All my
users are registered at ser, how can I get asterisk to accept all
inbound as long as they are from my ser proxy

tks

Iqbal
