Hi list,

We have devices since more then 4 years which where running well with
Asterisk. But with latest version (1.38 or more) we face problem with
those devices when they try to register. We got

[2011-05-14 17:18:06] WARNING[28559]: chan_sip.c:9950 register_verify:
Failed to parse contact info
< --- Transmitting (NAT) to XXX.XXX.XXX.XXX:5062 --->
SIP/2.0 400 Bad Request

Followed by

[2011-05-14 17:19:06] NOTICE[28559]: chan_sip.c:9502 check_auth: Correct
auth, but based on stale nonce received from
;tag=63d2ba80bffb016f’

Checking logs we found

Contact: *

in headers before the failed parse contact info.

We checked in source chan_sip and saw the parse info reject with Error
400 after “the auth is correct” comment.

We modified in sip.conf the type=peer in type=friend, same result.

Could someone explain us what happends here?

Thanks
