I've been trying to setup a VoIP system at home ('cause) and can call

my cordless phone (plugged into a SPA-3000) from a IP Phone (grandstream gxp-2000)

That's all good and works fine. I then decided to go further and plug the SPA-3000's FXO(?) port into my vonage ATA. I can get it to make outgoing calls, and sometimes even incoming calls.

I can't get authentication to work for outgoing, and I can't get caller id to work for incoming.

This thread was rather helpfull on getting the calls working.

..:

[spa_outbound] type=peer secret=<SECRET> port=5061 host=dynamic canreinvite=no nat=no qualify=yes dtmfmod=rfc2833 context=incoming-vonage

is my current outgoing config.

On the SPA I have the PSTN line registering seperately from the ATA line.

If I want to get things to autoforward to the server I need to set PSTN Ring Thru Line 1 to off and to set a dial plan to SO< s:@server.host:5060 > (And of course tell the PSTN which dial plan to use.)

If I set the CID on, asterisk 1.2.1 gets very confused about the source SIP address and chokes. I tried setting things to insecure=very but to no avail.

I'm thinking I might try openser, as its more sip orientated. (Though there documentation is quite sparse).

I found some documentation on the SPA-3000

Eric showed up to advertise his stochastic grammer techonology. http://computableplant.ics.uci.edu/papers/StochProcSemanticsTR.pdf

It appears to be a production rule -> result with a probablity Of course the various components can be mutualy dependent on various state parameters.

The question is can this be used for biological network evolution?

E.g. simplified cell cycle?
