[OpenSIPS-Devel] [ opensips-Bugs-3028327 ] nat_traversal damaged between r6844 and r6972?

[Richard Revels]

I do suspect this is fixed in the latest revision though.  I seem to remember that a call to parse the contact was somewhere in nat stuff to look for the expires time and the parsing was returning the tag rather than the contact or was returning the tag rather than the expires tag.  Can't remember exactly.  Anyway, there is a bugfix from Bogdan (rev 7008) that looked to me like it fixed the problem based on the description.

Did a quick look to SVN history, but wasn't able to find anything suspicious nat_traversal-related change. Just a wild guess: could it have been caused by the bug fixed in r7008?
