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...
