Hi Joegen,<br>
<br>
I just wanted to say a quick thank you for your advice - it worked.
As soon as I turned off all the NAT related stuff on the Aastra
phone (basically turned off rport and removed the stun and turn
servers), the phone stopped changing its VIA header and CANCEL
worked as advertised.<br>
<br>
In case it's useful to anyone else in a similar position, I have the
following NAT related stuff enabled on the internal FS sip profile
(note: my FS server is on a public IP i.e. not itself behind NAT):<br>
<br>
<param name="NDLB-received-in-nat-reg-contact" value="true"/><br>
<param name="NDLB-force-rport" value="true"/><br>
<param name="nat-options-ping" value="true"/><br>

Bummer - we've got an office full of these phones :(<br>
<br>
As you suggest, I'll turn off all the NAT stuff when I'm there on
Monday and see if that fixes it - hope so, otherwise I guess it
looks like I'll have to try and get Aastra to look at the problem
(doubt they are going to be very interested though!).<br>
<br>
Thanks,<br>

It's definitely a bug on the phone. I would try setting all
Aastra NAT related features off and see if it stops getting
confused like this. Freeswitch should be able to handle NAT
from the far end. <br>

Thanks Joegen, I hadn't picked up on that.<br>
<br>
Is there any valid reason why the phone would swap to using
it's internal IP (192.168.0.175) for the Via and Contact
headers when responding to the auth challenge? Or does this
look more like a bug with the phone?<br>

We are using Aastra 57i phones with the latest firmware

<br>
However, it looks like a specific issue with the Aastra
57i as I have just replicated the call and cancel
situation using a 3CX softphone and in this case the
CANCEL request gets honoured by FS.<br>

Here's a copy of a failed CANCEL test using the Aastra

<div>Also, try some other phone or device that does not
have the problem, and create a cancel situation the
same way and see if you can find a difference.</div>

When we make a call from an FS extension to a PSTN
number (via our ITSP<br>
gateway provider) and hang-up before the call
completes, FS replies to<br>
the CANCEL request with "481 Call/Transaction Does
Not Exist" and the<br>
call continues to ring on the remote end. If we
hangup after the call<br>
has connected, it works with no problem.<br>
<br>
I have looked through a SIP trace of this
happening and to my (untrained<br>
eye) nothing seems obviously wrong (i.e. tag, call
id and branch values<br>
all seem to be correct). I'm using the latest git
snapshot from<br>
