Re: [OpenSER-Users] OpenSER sending 483: Too many Hops

26 Mar 2008

Marcio,

you need the following line:
    alias=""spo.voip.br"

Right now you have only:
    alias=""vmw02-src.spo.voip.br"

Regards,
Bogdan

  Thanks Bogdan..but didn't work....I set the 
 "alias"(alias="vmw02-src.spo.voip.br <http://vmw02-src.spo.voip.br>

 <http://vmw02-src.spo.voip.br>" into "openser.cfg" and it`s 
 ok...passed in "vmw02-srv~#openser -c" but with the parameter
"listen" 
 didn't accept....(listen=udp:192.168.0.10:5060

     Hi Marcio,

     Try setting spo.voip.br <http://spo.voip.br> <http://spo.voip.br>
     as alias in your cfg.

     Regards,

  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 <http://192.168.0.10> <http://192.168.0.10>
 Client - 192.168.0.25 <http://192.168.0.25> <http://192.168.0.25>

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

 Does anyone know how to fix this ?

 Any hints.....??

 thx...
