[Asterisk-Users] Dynamically setting up/tearing down extensions

[Steven J. Sobol]

Hello, * newbie here,

I'm designing a setup that is to eventually be used in a production 
virtual PBX/VoIP service.

Customers need to be able to change their setups over the web - I want 
them to be able to do simple things like setting up call forwarding, as 
well as more intricate stuff that will require me to re-generate their 
dialplans. 

Administration of the service is to be web-based.

I'm looking at DynExtenDB (and have played with it). I love that it reads 
the dialplans out of a MySQL database - that is a critical issue for me. 
But it has some issues.

I have a test dialplan with one call to Playback() - just plays a wav file 
then exits. When DynExtenDB() is called, it adds one extra step that calls 
DynExtenDB_Free()...

--If I let the wav file play to the end, DynExtenDB_Free() is called 
properly. If I hang up prematurely, it isn't, and it also isn't called if 
I set the dialplan to dial out (for example, to forward the call to my 
cell phone).

--If DynExtenDB_Free() *is* called properly, and I then make another call, 
DynExtenDB() doesn't seem to be called again.

--I'm not sure that setting up a dialplan for extension 'h' is a good 
idea. What if I call, and then someone else calls and I hang up in the 
middle of the call? 

I am ready and willing to make changes to the source to DynExtenDB. In 
fact, I'd like to get it to a point where it could be used in a production 
environment. But I have a lot of questions before I can do that.

BTW, I have looked in the archives, and it's been suggested that maybe AGI 
is a better way to handle this sort of thing - but wouldn't the same 
issues still exist??

Thanks
   SJS
