[asterisk-dev] SIP REGISTER problems with Adit 3104

Tue Jan 31 12:47:56 MST 2006

We've got an Adit 3104 channel bank which also does SIP->POTS FXS
gatewaying, essentially a 24-line SIP ATA (which is how we're trying
to use it).  Note that the Adit 3104 is VERY different from the 600.

The 3104 does a SIP REGISTER for each POTS line on the same SIP
"call" using different "branches."

Under Asterisk 1.0.x, this worked using the global "pedantic=" option in
sip.conf.  Under 1.2.4 (branch 8905, actually any of the 1.2 versions
likely failed) the pedantic option does not appear to allow this
anymore, and I get:

Jan 31 09:05:15 NOTICE[26685]: chan_sip.c:6275 check_auth: stale nonce received from '<sip:5461 at bart.arlut.utexas.edu>'

messages when I do a "sip debug".  This is the same behavior I saw without
using pedantic on 1.0.x.  In short, Asterisk is unable to handle multiple
registrations on the same SIP call without pedantic because the call IDs
match and the tag isn't checked.

Looking at chan_sip.c, I notice in find_call() that the "To" tag
is being used in pedantic rather than the "From" tag as was
ultimately done for SIP/2.0 under 1.0.x.  I tried adding a similar
check for the "from" tag like what was done with the "to" tag, and that
worked.  However, I'm not sure exactly why the "to" tag is being checked
and not the "from" tag.

Can someone shed some light on this for me?  I think this may be a bug
in the SIP channel interface, but I want to check it out with someone
to be sure.

Some background tracing follows.

Thanks!
