[OpenSIPS-Users] Dialog module and uac_auth

[opensipslist at encambio.com]

Hello list,

A while ago it was clear that uac_auth is of limited utility,
due to the SIP RFC which requires that each message has a unique
cseq. Calling uac_auth from failure_route produced a new INVITE
with a proxy-auth header that didn't have a new cseq however.

Since the dialog module appeared, I'm wondering how if scripts
can be tweaked to use uac_auth in a SIP RFC compliant way.

...or is it still true that doing uac_auth() in failure_route fills
in the proxy-auth header of a INVITE message that has already
expired its cseq (no longer valid in the dialog)?

How can uac_auth be used with INVITE messages in a SIP RFC compliant
way?

Regards,
Brian
