Am working with Arun on this project - here's a longer description of the problem:<br><br>We've been fighting with our service provider on this issue - we seem to be getting a BYE just after we receive an ACK. They claim that it is an asterisk issue! The service provider provides only IP based authentication for inbound.
<br><br>We have used username-password based authentication with the same setup with *no problems* whatsoever! <br><br>If we configure an Audiocodes MEdia gateway to receive the calls, there is no issue - so there's something that asterisk is doing? or asterisk-Provider gateway combo?
<br><br>In our efforts to mask IP, I have used PROVIDER-IP for the IP of my service provider (host) and AsteriskIP to indicate my asterisk server<br><br>sip.conf<br>[PROVIDER]<br>type=peer<br>disallow=all<br>allow=g729<br>
