Hi Mark,

To be able to reach UA3 - which is not able to register - you can add a fix diversion for it in your config file. Guiding after the ser.cfg sample, you should insert in "uri=myself" section, before "lookup("location")" something like this: if (uri=~"sip:UA3@") { rewritehostport(ip,port); # this is not really necessary t_relay_to_udp(ip,port); break; }

ip:port is the location of the UA3 which must be fixed.

For calling from UA3, basically you don't need to do anything.

Best regards, Marian

Hi SER's,

I want to set up a private SIP network over a VPN using SER but some of my UAs are only able to operate in peer to peer mode (ie they cannot register). My proposed network architecture is the following:

UA1=192.168.0.4 UA2=192.168.1.4 UA3=192.168.2.4 SER=192.168.0.5

UA1 & UA2 can register with SER but UA3 cannot.

I have already set this up and have successfully made calls between UA1 &UA2. How do I set up SER to make calls from either UA1 or UA2 to UA3, or calls from UA3 to either UA1 or UA2?

Any help greatly appreciated! thx Mark
