clear timestamp when generating a fake empty frame to fix edge-case sending the same timestamp over and over

add sip_jitter_buffer_during_bridge which you can set to true to keep a jitter buffer on both ends of the call when you are NormT

play files saying vol level in conf in lieu of making a function of say modules to return file_string urls (we need that)
