Hi Folks,
I am not a SER user yet, but hopefully soon.
I have a need to interconnect two SIP networks just like we use a SIP to
PSTN gateway (to connect SIP network and PSTN).
Let me explain this senario in simple terms.
Lets say I have 1 port FXO g/w. Then all my clienst in the ip network can
use only one PSTN line to get to PSTN. And PSTN always thinks that the calls
are originated from the directory number of this PSTN line.
Similarly lets say I have 1 phone number, 1234(a)iptel.org ( one account from
iptel). And I have my own network of Phones in a private SIP network. I want
my clients to be able to talk to IPtel network just as the above senario,
where IPtel would think the call is originated from 1234(a)iptel.org. True
only one call at a time, just like PSTN senario.
How could this be done ?
It is not possible to do something like that just with SER because SER
is a SIP proxy and thus can't change From header field. You would need
a B2BUA for something like that.
But let me ask one question, what is it good for ? Why SIP user agents
in your private network should be able to make just one call at a time
?
