Hello Everyone,
My setup is kamailio as proxy with few boxes of freeswitch in the LAN. Having issue with
BYE when extensions register on different freeswitch boxes. Here are some trace of the
call.
Not sure if this tag= miss match or routing.
Dispatcher use group 0 with option 4 (round robin).

is group value 0 accepted? I think this may create problems if a
function returns the group in the config as return code -- iirc, this
was changed maybe for lcr or permissions.
On the other hand, the registrations are quite independent in SIP in
relation with calls. The BYE should be routed based on record-routing to
the freeswitch that was involved in routing initial INVITE, with no
relation to new registrations from end devices. Is the BYE sent to the
freeswitch that got the initial BYE.
Cheers,
Daniel
