[OpenSIPS-Users] Incorrect callid in ACK

[Mark Farmer]

Hi all!

I'm seeing a really weird issue where topology_hiding_match() fails to
match because of an incorrect Call-ID header but in a trace the header
looks correct.

I did think that it might be because of a missing fix_nated_contact() when
if (has_totag) is true so I added that but no change.

Is anyone able to point me at the issue here please?
