[Asterisk-Users] Snom-320 badly garbled audio

[Christian Stredicke]

You can always take a PCAP (Ethereal) trace from the phone's web page
and analyze it with the RTP Statistics tool in Ethereal. That should
give you a hint whats up with jitter & Co.

> My * server is running Asterisk 1.0.9, zaptel 1.0.9.1, libpri 1.0.9.
