Summary:                    Authentication seems to be broken again for SIP
NOTIFY requests
Description: 
This issue is the same as 9896? I am running release version 1.6.0.1 and
the sip notify sends out and I get 401 Unauthorized back This happens with
both Grandstream and Audiocodes devices. I had things working in 1.4 with
the 9896 patch and it was working in the 1.6.0 beta at one point but now it
is back to the pre fix behavior? Any help would be apperciated as I can't
reboot or force config updates without this working.

---------------------------------------------------------------------- 
More information - the NOTIFY goes out and receives a 401 back asking for
authorization. The packet is received in handle_response in chan_sip.c but
is dropped when __sip_ack sets ack_res false.

It appears the packet is never looked at thus the authorization code is
never reached.

This was the case the 1.6.1 and 1.6.2 versions.

SIP debug, Call history, and debug logs are attached in a single file

I'm new to the code so am not sure what the proper solution is. It would
be very useful for the Linksys phones we are using.

Thanks!
