[Asterisk-Users] Drivers etc [was] Voice Modem + Soundcard Driver

[Gary]

Actually with all this discussion about modem drivers etc...

Maybe, just maybe there is someone out there (Mark ?) who might add a
new driver to their wishlist and inform the list.

Problems are the actual modem chip MUST support FULL DUPLEX VOICE.

Which severely limits you to suitable chipsets & their are not many
chipsets which are suitable.

What we currently have is the usual problem of compatibility of
equipment between countries. Australia is probably the hardest on this
issue due to stringent regulations (& heavy fines) and the lack of a
reason market for payback on compliance testing etc...

The real things we really are missing a a device like a cisco ata-186
running IAX/IAX2 with at least one fxs & either a second fxs OR fxo
port.
