[Asterisk-Users] Asterisk on a dialup connection?

[Kerry Garrison]

Dialup quality is going to be very very poor to the point of not being
usable most of the time. You should use a service that has a low bandwidth
codec that works well like Skype or Teleo. The Codecs for Asterisk do not
like dialup. I have heard that Speex might work ok but I havent tried it.
Only Firefly supports it as far as I know.

Might work, but not well. Just have him install a softphone on his pc,
connect to the internet, and register on your * box. Use a high compression
codec. It is impossible to get g.711 to work over a POTS line.
