[asterisk-users] Registering Multiple SIP Accounts on One Server to Another Server

[Steve Totaro]

I was using IAX2 to send traffic from a PSTN/SIP box to a PBX and it 
worked fine except for audio issues that I believe are directly related 
to IAX2 in version 1.2.x.  I have four PRIs and want a separate context 
for each going into the PBX.  This worked very well with IAX.

I want to use SIP to see if the audio issues are eliminated but Asterisk 
does not seem to like multiple SIP account from one box to another (four 
to be exact)

I found this http://www.voip-forum.com/news.php?p=187 which makes me 
think this is a known problem.  Unfortunately, the link goes to an error 
page.

I have tried ever combination of credentials and setting in SIP conf but 
the calls still fail.  I tried friend, user, insecure=very, username, 
from user, and anything else I could think of.

Is there something I am missing or a workaround for this issue?

PSTN Box (4PRIs)--Each PRI has it's Own Context in sip.conf, SIP--> PBX 
(calls fail)
PSTN Box (4PRIs)--Each PRI has it's Own Context, IAX.conf--> PBX (calls 
work)

Thanks,
