[Asterisk-Dev] Wierd RTP timestamp?

[Iain Stevenson]

I have an application that gives results by playing back a file generated 
by Festival via the "Playback" option.  This morning, a Cisco 7960 drops 
two segments of speech whereas the same application works fine through an 
ATA186.  An ethereal trace contains this (.243 is the phone):

... timestamps look odd, like a chap reported yesterday, but then again I 
don't know RTP.
