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....
With the risk of being bashed on this list, I would propose that you use Asterisk as a PBX. It can register to SER, it's not a full-featured SIP proxy as SER, but have the functions you need on the PBX level. Voicemail, conferencing, call groups and a lot more. SER and Asterisk is a good combination in the scenario you describe.
Maybe this is a stupid question, but would it be possible to use SER and Asterisk together to provide (group) call-pickup functionality? I know Asterisk can do it, and I know SER can't do it.
Maybe forking the INVITE to both the user and Asterisk?
