[OpenSIPS-Users] OPENSIP 3.4 send_reply and tight matching failed

[Bogdan-Andrei Iancu]

HI Alan,

I suspect a scripting issue, making the received hop-by-hop ACK (for 
negative replies) to be "handled" by the dialog module, which treats it 
as a end-2-end ACK (for 200 OK reply).

I guess your script lacks this block 
https://github.com/OpenSIPS/opensips/blob/master/etc/opensips.cfg#L112 
when comes to sequential requests; this block needs to be before the 
loose_route or any dialog/TH matching.

Regards,
