Hi all,
I have tried to reproduce the issue using Sipp tool. I have added extra
paramets of rport=5060 in Via Header . made call between Voip1 & Sipp tool .
For the Cancel sequence my Voip responds with ACK.
I cannot point its an issue with Voip-1 ,because it works with toher servers
responds for 487 with ACK.
I have attached my Sipp script . Please let me know is there anything wrong in
this script.
Iam not sure whether it's a valid question to post here.
for refrence I have attached my cancel.txt fiel here.
Best Regards,
Ckumar.

Yes, the via is malformed
Via: SIP/2.0/UDP
10.32.140.122:5060;rport;branch=z9hG4bK-38-dc39-6b4deb27;rport=5060
(rport)+ (rport=5060) equal trash.

Look at the cseq; the 200 is for CANCEL. However the 200 has a
malformed Via entry.

The ordering is irrelevant; the UAC must accommodate either order.
The issue is the malformed Via entry. The via issue appears to be
causing the UAC to ignore the 200 response and ignore the 487 response.

I disagree with that statement. That statement even conflicts with the
typical CANCEL flow shown within RFC 3665 section 3.8. RFC 5407
provides some atypical CANCEL flows.
