asterisk users - Dec 2004 - Packet flow in relaying from SER to Asterisk

Hi,

I know the following is mostly the issue of SER and I already posted the
same content to SER User list. Just for more input, I posted it to this
list. Sorry for the cross post for some people.


I've set up SER for UA to UA call.
I'm thinking of setting up SER to relay to Asterisk PBX to use conference
call and voicemail of Asterisk.

I will employ this system for client connection over global IP network.
Actually My SER is running in three IPs -global, private and IPv6 and
Asterisk is also running on the same Linux box with different private IP
from SER.

Here, I have a question regarding relay from SER to Asterisk.

Does Asterisk SIP channel should listen to global IP?
By that I mean I don't understand how t_relay works.

Say, when my party members make connection from different global IPs to my
SER on global IP, is that possible to relay that connection to Asterisk
running in the same Linux box with private IP and different port number?


On Global Ips     Linux Box running two servers
                  _____           _____
SIP Phone --------|   |           | A |
                  |   |           | S |
SIP Phone --------| S |           | T |
                  | E |-----------| E | Asterisk running on
SIP Phone --------| R |           | R | private:192.168.0.12:5070
                  |   |           | I |
SIP Phone --------|___|           | S |
                                  | K |
  SER running on ...              |___|
  global:61.194.32.77:5060
  private:192.168.0.12:5060
  ipv6:[2001:268:304:a300::10]:5060
  *For NAT solution, MySTUN & MediaProxy is employed*


In the above setting, can UA (SIP phones) on global network use conference
call of Asterisk? In other words, can SER relay from its global connection
to local private network? If possible, what can be the syntax in ser.cfg?

Thanks in advance and deep sympathy to Tsunami victims in South Asia
