Description:This patch allows you to set the number of frames per rtp packet.  Some gear requires 30ms g729 ... some needs 30ms g711... This allows you to tweak those settings in rtp.conf.  It does have some sanity checking to allow sane values.

In the config, I think we need to add something like

"If you change the lenght of the RTP packet in Asterisk, you have to have the same setting in the phone. If you have different settings on each side of the call, you will get very poor sound quality."

...until we get a working RTP clock for timing of outbound packets.

That satement is actually FALSE you will have perfect audio quality if each end is mismatched.
