I think the phone is making a mistake with the CANCEL packet.<br><br>Here is the Via header from the INVITE the phone sends:<br>Via: SIP/2.0/UDP 190.137.190.131;rport;branch=z9hG4bKac109601000000fb4ad814425106977400000792<br>
<br>Here is the Via header from the CANCEL<br>Via: SIP/2.0/UDP 10.0.0.8;rport;branch=z9hG4bKac109601000000fb4ad814425106977400000792<br><br>it's identical aside from the private address contained in the CANCEL and a public one in the INVITE<br>
<br>So the anti-nat settings on your phone are not working properly and they forgot to substitute the public IP for the CANCEL.<br><br>That makes Sofia unable to match it to an existing call.<br><br><br><br><div class="gmail_quote">

Hi guys,<br>
<br>
I'm having a signaling issue on FS when calling from an endpoint to a<br>
GW.<br>
To reproduce the error I just call and hungup the call right away.<br>
FS gets the CANCEL and replies back with 481 Call/Transaction Does Not<br>
Exist, so the call continues and eventually connects, even when the A<br>
side of the call is closed.<br>
I have verified that the Call-ID of the CANCEL matches that from the<br>
INVITE, so I see no reasons for FS to reject it.<br>
<br>
SIP+FS logs in pastebin 10738.<br>
<br>
Any ideas?<br>
<br>
Thanks,<br>
Rogelio<br>
<br>
