Hi,
 
all your phones need to be register with SER. The asterisk will be just PSTN
gateway, voicemail server or something else (I prefer to forward all the
calls from ser to asterisk because it's easy to manage the dialplan). I have
the same configuration, I balance the traffic with SER and I use realtime
with asterisk servers.
 
Best regards,
 
Chris HARIGA

Subject: FW: [Asterisk-Users] Nat + Asterisk + Ser (Far end Nat Traversal)


 Hello,
 
I have several * servers behind a SER server (in a local ip range). The SER
server is also publicy reachable. On the other site, I have SIP clients that
are behind another NAT or in the same NAT range as the * server. Can someone
give me some directions/hints etc. on how to make this work. I think I
should be using MediaProxy with SER. But do the SIP clients need to register
at the SER server? If not, how will the reach the * server, since they're
only reachable VIA the SER router.
 
Here's is scheme:
 
 
 
   -----                                                      IP Phone A
(Behind NAT router) (ext 100, Asterisk A)
   - *A-----|        priv. addr   publ. addr                 |
   -----    |               -------         INTERNET         |
            ----------------- SER ---------------------------|
   -----    |               -------                          |
   - *B-----|                                                 IP Phone B
(Behind NAT router) (ext. 100, Asterisk B)
   -----
 
 (Asterisk servers)
 (10.254.254.x)   
 
 
Phone A can belong to Asterisk A, and B to Asterisk B. 
 
Hope this give you enough information.
 
Regards,
