Could you be more clear? Are you just asking how to put an iDEN phone into Trace Mode, or is thee a specific mode that you seek that is different than Trace Mode?

Please clarify "decode audio from an iDEN channel".

The old analog phones had a feature that would allow one to hear any audio that is being transmitted over a particular channel.

Does any iDEN phone have that test feature?

Tks,
