I just start using OpenSIP and trying to get myself familiar with OpenSIP and it's config files, method etc.<br><br>Well, I am trying to achieve following:<br>Client IP: x.x.x.x<br>OpenSIP: y.y.y.y<br>Asterisk: z.z.z.z<br><br>1) Client -> OpenSIP (Load_balancer) -> Asterisk1, Asterisk2....<br> a) If Client Request is Register -> Relay to Asterisk (It is working fine as peer is defined with user/passwd auth, host=dynamic)<br> b) If Client Request is INVITE -> Relay to Asterisk (Asterisk Reject as peer is defined as IP Auth, type=peer, host=x.x.x.x)<br><br>"b" scenario failed as Asterisk read OpenSIP IP y.y.y.y and reject the call as Asterisk is expecting Source IP x.x.x.x instead of
y.y.y.y<br><br>I tried following to fix but no success:<br><br>1) 302 Redirect for GW Clients, who can only authenticate by IP and don't support registration with user/passwd. But my DID Provider don't support 302 redirect although i have tested with Eyebeam Client in peer to peer mode and it works. But as it didn't work with my provider so I tried another way:<br><br>2) uac_replace_from & uac_replace_to function of uac.so module, I tried to replace from/to field with client IP but still Invite is from OpenSIP IP y.y.y.y and again Asterisk/Voipswitch (another switch) reject call. <br><br>If required I can post my config file as well here or pastebin for your expert reviews. I would like to know if it is possible to achive above scenario with OpenSIP, if Yes then how, any example would appreciated.<br><br>Another small problem is that while setting up 302 redirect I wanted to pass $du value to rewritehost("") as $du have the address return by
load_balancer of destination IP and rewritehost() only accept string. Looking for suggestion on this as well.<br><br>Hopefully to receive positive reply by community.<br><br>Thanks<br>Regards,<br>Muhammad Zulqarnain<br>MSN: zulqarnain@globalitvision.com<br></div>
