Hi Folks,
I have a problem with a registrar module (at least I suppose so). When A
calls to B, in some specific situation, B receives two INVITEs. This mostly
(not only) happens when one account is registered on two or more UAs. In
this situation the extra INVITE is sent only to the one that is second in
the list (kamctl ul show ACCOUNT).
kamctl ul show Alice:
Contact:: <sip:orlvuzyd@192.168.28.72:52129
;q=0;expires=1916;flags=0x0;cflags=0x40;socket=<udp:8.8.8.8:5060
;methods=0xFFFFFFFF;received=<sip:8.8.8.8:52129>;user_agent=<Blink 0.2.5
(Linux)>
Contact:: <sip:Alice@192.168.28.51:5060
;q=;expires=3061;flags=0x0;cflags=0x40;socket=<udp:8.8.8.8:5060
;methods=0x129F;received=<sip:8.8.8.8:5060
;user_agent=<Linksys/PAP2T-3.1.15(LS)>
My situation.
1. Alice calls to BOB.
2. kamailio looks up in location table for BOBs registrations
3. in DB there are two rows (two devices(linksys PAP2T and Blink(blink is
the second one)))
4. kamailio send 3 INVITES ( linksys, blink and blink). Every INVITE has
different via.branch
(Via: SIP/2.0/UDP 8.8.8.8;branch=z9hG4bKe2d7.009b1df2.1)
(Via: SIP/2.0/UDP 8.8.8.8;branch=z9hG4bKe2d7.009b1df2.2)
(Via: SIP/2.0/UDP 8.8.8.8;branch=z9hG4bKe2d7.009b1df2.3)
All my registrar parameters are set to default.
Nothing is looping on interfaces.
I have no idea whether this is a bug or my missconfiguration.
Thanks for replies.
Kind regards,
Efelin Novak
