Hi,

If anybody can take a look openser.cfg below. I`m working vmware
(enviroments virtual)...Whenever I try a "register" a client I get 483: Too
many Hops....as if he had a loop (config file) but I am unable to find the
problem...

I use OpenSER 1.3-notls, client softphone: twincle or xlite...

OpenSER - 192.168.0.10
Client - 192.168.0.25

Bind9/named.conf(SRV, A): spo.voip.br


Does anyone know how to fix this ?

Any hints.....??

thx...
