Hi Bogdan,
The problem is triggered when from mangling is involved and t_relay is
used in manual mode and 100 Trying is not sent.
An INVITE comes in. It's From headers is mangled and then is sent out
(using usrloc lookup). The INVITE is relayed using t_relay("0x01")
and no "100 Trying" is sent out.
On the first INVITE retransmission, the bug will occur.
Regards,
Ovidiu Sas
