[sipxtapi-dev] Stopping Flow Graph for Calls on Hold

[B Kaser <blkaser@xxxxxxxxx>]

I am writing a client phone application where the is one active call and a significant number of other calls on hold.  I notice that even though there is no RTP for these calls, the CPU utilization increases with the number of calls.  This seems to be due to processing the flow graphs.  Is it possible to stop the flow graph when the call is put on hold and the restart it again when the call is taken off hold?

Thanks.
