Hi,
I use PJSIP version 1.14.2 which have support for RFC 4028 - Session Timers
In SIP. And I have the following problem:
1. User A send INVITE without RFC 4028 header to Huawei SSW
2. User A receive 100 Trying from Huawei SSW
3. Huawei send INVITE with RFC 4028 header: to User B
Session-Expires: 600\r\n
Min-SE: 600\r\n
4. User B send Trying to Huawei
5. User B send 180 Ringing to Huawei
6. Huawei send 180 Ringing to User A
7. User B send 200 OK with RFC 4028 header: to Huawei SSW
Session-Expires: 600;refresher=uac\r\n
8. Huawei send ACK to User B without RFC 4028 header
9. Huawei send BYE to user B:
Reason: SIP;text="Session Timer Check Message Failed for INVITE 2xx"\r\n
Does anyone have any idea where the problem is?
Regards, Branko
