The major issue you'd have in trying to build a CO (class 5) switch out of Asterisk -- ok, one of a dozen major issues :-) -- would be that you need to speak SS7 to The Network... which means, quite apart from the fact that you need Asterisk to know how to speak SS7, which I don't know if it does or not, that you need something with an SS7 interface system that's certified by the carriers.

What good does that do you if you are approaching this from standpoint of a CO switch? About the only thing you can do with Asterisk that would even remotely approximate a large-scale TDM switch is confer upon the sagacious qualities of an all-knowing call controller and enclose it in a shatterproof fortress of high-density media gateways like the Cisco AS5400 5800, and dump TDM trunks into them. Then you can send and receive calls from TDM in a fairly high volume as SIP and perform some manner of rudimentary switching. But it's not a true signaling / call controller. It has no awareness of the state of the controllers in the MGWs, nor advanced signaling capabilities (i.e. SS7, native TDM or otherwise). Because of this, you cannot make your TDM interfaces scale; you cannot tell the MGW which trunks to use for what purpose and when, and you will have to dedicate MGWs to certain concrete purposes (inbound, outbound), which puts a serious damper into 99% of the economies of scale for which a switch is actually beneficial. -- Alex Balashov Evariste Systems Web: http://www.evaristesys.com/ Tel: +1-678-954-0670 Direct : +1-678-954-0671 ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [asterisk-users] Sort of OT: PBX vs CO
Just one question, why would the Asterisk be involved in the voice path at all ? I would assume a media gateway (TNT ?) would be the obvious choice to provide trunking side. And, for line side another gateway (not so sure would be as often seen), but in this case a Line side gateway, and again, * would not need to be in the voice path. I know that TNTs with DS3 cards have been used by persons in this mailing list, and I assume that some vendor of Line gateways (mediatrix/someothers for low density, I guess some genband/calix/occam/whatever for higher density) would not have problems getting their gear to work with Asterisk. The missing piece would be the SS7, that I understand others have used with * also here...so... (regarding VOIP not being an option, I have to wonder, for how long :-).. NGN vendors don't use a TDM switching fabric (example, Nortel CS2Kc has no 'ENET' or anything like that), why would Asterisk need one .. Alex Balashov wrote: On Fri, 10 Aug 2007, Jay R.
