Pardon my ignorance, but I was hoping someone could clear up something for me.
- For a few POTS lines, digium has a single port card for that, or a T1 card to a channel bank. - For 10 or more lines, digium has a T1 or E1 card for that too based on PRI channels - For 100's to 1000's of lines, I suspect a soft-switch is in order??? A traditional phone company will sell: - POTS lines for small quantities - PRI channels over one or more T1 lines - ??? for 100's to 1000's of lines??? Unlike PRI channels, we are all able to get better than 64k using a variety of different codecs. So how is it possible to get more out of a link/bridge (pardon my lack of proper technical terms) to the public phone systems?? If a codec can drop a channel down to 8k, then a single T1 should be capable of supporting nearly 184 concurrent calls right?? I suspect this is where a softswitch comes in, but it is not clear to me. Do you call up a phone company and ask for a block of T1's using SS7 signalling, or MGCP, and plug it into a softswitch?? If that is even partialy correct, does that decrease the cost (HERE IS THE KEY) for access to public lines? I'm sure the softswitch (again assuming I'm partially right) costs around $100k. Asterisks shows support for MGCP channels, does that help in this fuzzy scenario? Perhaps I am way off, but I do hope someone can clarify some of these things for me, or at least get a laugh at my quesions and wording <grin> Cheer, Darren _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
