[Twisted-Python] Unhandled Deferred Error

[Godson Gera]

Hi,

This error is obviously raised when the issued command is failed to execute
at Asterisk end. However there could be variety of reasons for failure, one
common cause is call is hungup on which the command is issued.

By looking at the error it occurs that you might be trying to play some
audio file on the call. So check if the file really exists and is in the
format specified by Asterisk 8000Hz mono 16-bit . Looking at the Asterisk
console while this occurs will also give you useful cues.

As Paul mentioned this is really a starpy and Asterisk question, so posting
queries like this on starpy mailing list will get better insights.
