Description:ASTERISK-1837 introduced support for RFC3581 (adds rport parameter to Via field in SIP header).  Unfortunately, this breaks some clients that do not support this (ie: Uniden's UIP200).

I'd like to request that RFC3581 be made an option, either globally, or on a 'per client' basis in sip.conf.

How does it "break" a client?

sorry, should have been more descriptive.

The UIP200 sip phone will not respond to INVITE requests that contain ';rport' in the Via field.  
ie: If you try to call a Uniden phone, the phone will not ring.

If I remove ';rport' from the via in chan_sip.c, then all will work again.

You should now be able to use "nat=never" to to specifically force the rport to be omitted.

Please confirm it fixes it for you as soon as humanly possible as I am leaving for Europe very soon.

Markster,

Yes, this fixes the problem.

Thanks!
