[Asterisk-Users] D/41 ESC dialogic ISA CARD

[Steve Underwood]

Hi Scott,

It cannot play and record at the same time. It can play audio and listen 
for DTMF. It can record audio while listening for DTMF. That is about 
its limit. Most Dialogic cards are like this. The newest JCT cards 
permit full duplex operation, but still have issues with excessive 
latency, when used for VoIP. Their duplex capability was added for 
speech recognition users, where latency is not a big issue.

Regards,
Steve
