+; Configure jitter buffers in zapata (each one is 20ms, default is 4, max is 32).
+; The zaptel jitterbuffers differ from IAX2 jitterbuffers in that they serve 
+; to queue data that is being written to the zaptel interface if the write 
+; needs to be put off for a moment. An excessive value simply wastes memory
+; however too low a value will result in choppy audio leaving the zaptel 
+; interface and reams of console messages along the lines of:

+;         unavailable) on channel 1 - audio may have been lost
