[arm-allstar] Connection glitches

[wb9rsq at gmail.com]

I should have added that in the past I have successfully streamed 256KBPS
stereo audio for several weeks between these two points.
During that time I never heard even a slight break in the audio. Didn't
listen all the time but over several hours on most days it was completely
clean and glitch free.
That is one of the reasons I thought these would make good end-points.
I am running both nodes in duplex0 using them for accessing my repeater from
an ht.
Ht at one end and a base radio at the other.

Tell us a little more about the point-to-point connection?

The most typical cause of these types of issues is poor network quality, 
where several packets are lost back-to-back.

Another cause of these issues can be sudden, big changes in 
network latency. Usually asterisk will automatically compensate for 
latency changes, assuming the jitter buffer mechanism is turn on (it is by 
default in HamVoIP). While asterisk is adjusting the jitter buffer, you'll 
have a few audio dropouts. But, this should rapidly settle down.
