[OpenSIPS-Users] retransmissions after 1xx response

[Bogdan-Andrei Iancu]

Hi,

First of all version 1.7 is really outdated...you should consider 
migrating to 1.11 or 2.1 (maintained versions).

Based on what you say it looks (for whatever reason), your opensips 
either does not receive, either ignores the provisional replies (100 and 
180).
