[SR-Users] Registrar module creates an extra branch

[Efelin Novak]

Hi Klaus,

thanks for a prompt answer.

Third INVITE (extra) is sent to the blink, but only if the Blnik is second
in the location table. When the Linksys is second in the list, only two
INVITES are being sent.

No nothing is looping, it acts like there are 3 separate rows in the
location table.

Kamailio creates 3 branches from two AOR. Extra INVITE differs from the
original one only in via branch xxxxx.{0,1,2}.

Regards,

Efelin Novak
