I'm trying to get simple register replicated across 4 servers sharing the
same sip
domain. A user can register to any of the proxies. I have 1 major problem
with this setup
and a slightly minor one.
1) NAT does not work at all, why ? if the call goes to the wrong proxy no
deal!, Is there a way
I can force the Invite to go via the registering proxy ? Call without NAT
work 100%.
2) the third server I forward the register to ends up getting 4 Via
statements? Is this proper?
I have attached a sample trace of the (minor) issue and a snippet of my
config file.
I'm close to wits end here. Any ideas most welcome.
I have tried using t_replicate but it only sends to one server as per TM
docs. how do I
setup ""If multiple destinations are to be used, the additional SIP URIs
have to be set as branches."" as per
TM module?
thanks.
