[SR-Users] Registrar module creates an extra branch

[Efelin Novak]

Hi Folks,
I have a problem with registrar module (I suppose). When A calls to B, is
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
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 at 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 at 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
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.

I have no idea whether this is a bug or my missconfiguration.

Thanks for replies.

Kind regards,

Efelin Novak
