I'm developing an application for a project that's only concerned with recording incoming DTMF tones. The aim is for the UA to accept many calls, perhaps 10+ simulatenously and record all the DTMF tones coming in for each individual call.
The question is, how do I go about ignoring the speaker output altogether. I figured one way was to memset psamples to 0, through a speaker hook callback, but I was wondering perhaps if there was a better way.
I'm hoping to reduce resource usage by completely taking the audio component out of the system since I'm not concerned with that. I'm with the understanding, that sipXtapi can send me media info events of DTMF tones without the need for an incoming audio stream.
I'm also trying to do this without directly changing anything in the sipXtapi library, and doing this solely through calls contained within the sdk.
Thanks,
