Jan,
Thank you for the response.
The longer I use the SER proxy server, the more uses I
find for it.
What I am currently envisioning is this:
I run a PBX PROXY server for a specific business
customer. This customer has a private naming (numbering)
plan. The names of the UA devices are 101, 102, 103, etc..
These are 'extension numbers'.
I would like to be able to make the PBX 'pretend' it is
the phone. It will send a REGISTER to the GATEWAY, and then subsequent
INVITES for that number will be sent to the PBX. The PBX will
determine how to deliver the call using local rules on the
SER proxy. The rules will be something like:
business days between 9am and 5pm forward all incoming calls to x100.
If extension 100 is busy (or doesn't answer), roll to extension 101.
If extension 101 is busy (or doesn't answer), roll to voice mail.
And a million other things.
I realize that I can forward the call from the GATEWAY
to the PBX, but, I think it would be MUCH cleaner if
I could tell the SER PBX engine to REGISTER a number....
Make sense?

Greg,
it would be possible with some shell script magic. It is possible to
send a REGISTER message using the fifo interface.
Before we dig into into it, let me ask what is the reason for doing
something like that ? Can't you simply forward the SIP messages from
GATEWAY to PBX and if PBX is off or crashed then the GATEWAY will send
"Request timeout" to the PSTN (instead of 404) ? Or am I missing
something ?

Hello,
I have a SER server, it has 2 phones
registered to it. The phones are 300000
and 300100. The registration works fine, and
I can place calls between them. I am calling this
my 'PBX'.
I have another SER server that can connect to
a PSTN. I can register my phone number with it,
and I can make and receive calls from the PSTN.
Let's say that phone number is 2145551212(a)addaline.com.
I'm calling this my 'GATEWAY'.
OK, here is the tricky part. I would like to make
the SER 'PBX' *REGISTER* 2145551212(a)addaline.com with
the SER GATEWAY ... just like
it is a UA. So an incoming call to 2145551212 would
get delivered to the SER PBX, and I'll figure out which
extension gets the call with local rules. For very
simplistic delivery at the PBX I can alias 2145551212 as
300000.
If the PBX crashes, or is turned off, the 2145551212
registration will eventually evaporate.
Anyway, I can't figure out anyway to get SERPBX to register
with SER GATEWAY.
Is this possible?
