Hi Razvan,
It's my opensips generate second BYE:
First BYE not
generate, just transmit to provider:
_U 1.1.1.1:5060 ->
3.3.3.3:5060_
_BYE sip:3.3.3.3:5060;transport=udp SIP/2.0._
_Via:
SIP/2.0/UDP 1.1.1.1;branch=z9hG4bK6f1e.1ae76cf3.0._
_Via: SIP/2.0/UDP
1.1.1.1:5060;received=1.1.1.1;rport=5060;branch=z9hG4bKc70647f52389844ecd8d1103e651514c._
_ROUTE:
._
_From: "Direction" ;tag=9592a99927b4cd21._
_To:
;tag=sip+1+347c0010+ea2ac41._
_Call-ID:
c2fb7803cb9af9e4d85b965d731259a0 at 192.168.254.200._
_CSeq: 1613414671
BYE._
_Contact: "Direction" ._
_Max-Forwards: 69._
_Allow: INVITE, ACK,
CANCEL, OPTIONS, BYE, REFER, NOTIFY, INFO, UPDATE._
_Supported:
timer._
_Content-Length: 0._
_._
Second BYE generate by my proxy:
_#_
_U 1.1.1.1:5060 -> 3.3.3.3:5060_
_BYE
sip:3.3.3.3:5060;transport=udp SIP/2.0._
_Via: SIP/2.0/UDP
1.1.1.1;branch=z9hG4bK6f1e.1ae76cf3.1._
_Via: SIP/2.0/UDP
1.1.1.1:5060;received=1.1.1.1;rport=5060;branch=z9hG4bKc70647f52389844ecd8d1103e651514c._
_From:
"Direction" ;tag=9592a99927b4cd21._
_To:
;tag=sip+1+347c0010+ea2ac41._
_Call-ID:
c2fb7803cb9af9e4d85b965d731259a0 at 192.168.254.200._
_CSeq: 1613414671
BYE._
_Contact: "Direction" ._
_Max-Forwards: 69._
_Allow: INVITE, ACK,
CANCEL, OPTIONS, BYE, REFER, NOTIFY, INFO, UPDATE._
_Supported:
timer._
_Content-Length: 0._
After this message, my provider (3.3.3.3)
send error 500 (SIP/2.0 500 Server Internal Error).
The senario is
repeated at each call, even with different UAC.
If the BYE is generated
by my provider (3.3.3.3) there is no error.
Ex:
My customer BYE -->
Proxy --> Provider = Not OK error 500
Provider BYE --> Proxy --> My
customer = OK
regards.

You will see exactly who sends the second BYE.
