[SR-Users] BYE dispatcher

[Slava Bendersky]

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).
