[OpenSIPS-Users] opensips_head b2b with SEMS 1.2.1 - Bad ACK ?

[Anca Vamanu]

Hi,

What opensips version are you using? I fixed a similar problem last week 
- it is not that the ACK is not passed on the other side - because it 
is, but that at OpenSIPS the received ACK is not matched with its 
transaction. Please take the code from svn branch 1.6 or trunk.

Regards,
