First of all, the Allstar Autopatch subscription is per SERVER, not NODE. All the nodes on any server, by inherent design, share autopatch accessibility.
There is not so much as a SINGLE manufacturer of an FXO card that will provide sufficient quality, especially in the area of trans-hybrid loss, for radio autopatch (full duplex) use, without hardware echo cancellation, which is going to be a DARNED EXPENSIVE CARD!!!! Nor will any ATA!!! Even current FXO cards with H/W echo cancellation *REALLY* sound CRAPPY when used this way.
Don't do it. Don't try it. It won't work. That is reality.
Now, for those of you "poised" to press the reply button and share your "wealth" of advice on how "gee, it works fine for me", I am just going to say, "in this case, just don't". Trust me. I invented this technology (Zapata Technology/Zaptel/DAHDI). I understand why it works, and why (in this case) it can't (in great detail).
I certainly acknowledge that there have been a number of really good open S/W echo cancelers contributed to the Asterisk project, especially the one that David Rowe wrote. Even it can't "forgive" a poopy hardware FXO implementation (which they ALL are) along with the SUPER DEMANDING (well in excess of normal telecom) needs of a two-way radio full duplex autopatch.
I dedicated a vast part of my life, to, amongst other things, making reasonable *FOUR WIRE* telecom interfaces available to *EVERYONE ON THE PLANET*. Previous to Zapata/Asterisk, we were all *FORCED* to use 2 wire (standard POTS) for things that *REALLY* required a trunk (4 wire) for proper quality and control. We can now. And its so incredibly inexpensive. It makes me smile!! Take advantage of it.

Hi
in trying to figure out a good way to implement auto-patch on a linked system.
I keep several repeaters linked full time, some via my existing system with a ALLSTAR node connected to a port on the controller, others via ALLSTAR directly. thus I feel it would be more efficient if 1 patch served all.
Can 1 node share its auto-patch with other nodes or do I need to have a separate patch for each node? Also I would like to use a PBX (not sip) extension if possible.
If it is possible to share one auto-patch between nodes could I place a FXO card in the HUB node computer and share that connection?
please let me apologize if this has been covered but I could not find it.
thank you for your help.
Chris
