Summary:                    Asterisk does not use the “expires=” from the
SIP contact header during registration
Description: 
When registering against a SIP provider, the reply from the registrar (SIP
200 OK message) includes an “expires =” in the SIP contact header, but
Asterisk always use the “defaultexpiry” value instead.

Example:
------------
Asterisk sends “Expires: 3600” when register, but if the registrar
replies with “expires=3170” in the contact header, then Asterisk always
scheduling for a reregistration in 3585 s. anyway, and therefore the
registration expires before Asterisk sends a reregister.

I have tested with Asterisk versions: 1.6.0.5, 1.6.0.3-rc1, 1.6.0.9,
1.6.1-beta4, 1.6.1.0, 1.6.1.1, 1.6.0.13, 1.6.1.4, 1.6.1.5, 1.6.1.6,
1.6.1.7-rc1 and SVN revision: 219891 (Asterisk SVN-branch-1.6.1-r219820).
The problem seems to exist in all above versions.

With Asterisk 1.6.2.0-beta3, beta4, rc1 and rc2 the registration doesn’t
work at all.
SIP/2.0 403 Forbidden 
(WARNING[3584]: chan_sip.c:17273 handle_response_register: Forbidden -
wrong password on authentication for REGISTER …)
;I will attach the debug output for the 1.6.2.0 registration problem in a
new issue!
