[SR-Users] Problems with dispatcher module | feature disabled

[Daniel-Constantin Mierla]

Hello,

it looks like sock_avp parameter has to be set -- it is there before
4.3.0 release, as I could spot in 'git blame' for dispatcher.c:768.

Not sure is really needed for failover, I will check its usage when I
get first chance.

http://kamailio.org/docs/modules/stable/modules/dispatcher.html#dispatcher.p.sock_avp

Cheers,
DAniel
