Woof! Raymond asked me this question. I open it up to the wisdom of sipx-dev. I think the essence of the question is: When using DNS SRV, when an INVITE is challenged, should you then send the new INVITE with the credentials back to the server that requested them, or do you start the DNS SRV lookups all over again, potentially getting a different server? --Woof! ------- Forwarded message ------- From: "Raymond Chandler" <[email protected]> Subject: DNS SRV Mike Jerris told me to email you in regards to the proper handling of DNS SRV records for SIP. Specifically, we have an issue with sending INVITEs to a proxy, getting challenged and sending INVITE w/auth to another proxy since all have the same priority and weight. It was said that if the weight is 0, then the first chosen host should be used throughout, but any other weights would cause the normal selection process to occur on every new transaction. The references we've been going off of thus far are RFCs 2782, 3263, and 3261. It would be greatly appreciated if you could shed some light on any other resources that we might be missing that say one way or another that we're handling things the right or the wrong way. BTW, I'm on IRC as [intra]lanman if you'd rather contact me there. Thanks, Raymond Chandler http://freeswitchsolutions.com http://cluecon.com http://cudatel.com --Woof!
