Pardon me for asking, but I'm not aware of some of your acronyms. What is TDM, SIP, and CMG with respect to this discussion. You've gotten my curiosity up, since I just heard that a local company here in the Dayton area has a pallet of Askersik phones that they are about to get rid of. Some are in original boxes that were never used. I was thinking we should get 4 or 6 to keep for our local computer museum project. Interesting discussion even though I have no experience in phone equipment.

I have a CMG card myself but haven't done anything much with it, and using TDM is really the proper way to set up a channel bank
That's the way we do it at LSSM for our internal dial-in pool and BBSes. TDM is so much simpler and free of hassle compared to SIP.
That, and it's significantly more feature rich, when dealing with analog phones. There's a lot of cool stuff you can do with TDM that you just can't do with SIP. From what I understand, VCF Midwest also uses real TDM at their conference and not SIP.
Yep. I was going to stop short of saying "SIP is a steaming pile", but I'll go ahead and say it: "SIP is a steaming pile".
(I'm also a bit biased, I'm the primarily developer of TDM related stuff in Asterisk nowadays.)
Oh, very cool. I did some work for Digium (Solaris drivers for some PCI cards) about twenty years ago. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
