[OpenSIPS-Users] Problem with 200 OK after BYE

[Dragomir Haralambiev]

Hello,

I use Opensips 2.3 in follow scheme:

SBC -------Opensips ------Zoiper

When Opensips Send BYE to SBC, SBC not return 200 OK.

Zoiper send BYE to Opensips.

    BYE sip:Opensips_IP:Opensips_port;did=363.27c9faa4 SIP/2.0
    Via: SIP/2.0/UDP
Zoiper_IP:32346;branch=z9hG4bK-524287-1---fed42b1d179cd7b0;rport
    Max-Forwards: 70
    Contact: <sip:555222 at Zoiper_IP:32346;transport=UDP>
