[asterisk-users] TDD - stops receiving characters

[Warrick Zedi]

We are working on a TDD application and testing with an Ultratec 
SuperPrint 4425 in Australia.

We've got it to exchange characters fairly cleanly for a minute or two 
but after that we seem to be getting a signal but no character in Asterisk.

Has anybody done any work with the Asterisk TDD functionality and got it 
to work reliably? Does anyone have any idea what might be causing the 
system to stop receiving characters after a particular period of time?
