The latency is between 600ms to 1200ms depending on all sorts of
things. You are correct in stating that this is a serious issue.
There is certainly no way to 'fix' this. We do all sorts of crazy
things like quadrupling the originating packets and using a type of
ack inside of a tunnel/tap. Sending pauses in speech and silence as a
pattern rather then each packet of silence individually. Buffering
half a second of audio and having more of a CB style conversation than
traditional 'telephone' use. It " " Works " " :)
This solution was for a generator + ups + gps + articulating arms for
satellite positioning + 2.4ghz wireless b/g + 2 hard phones and a pre
configued caching server.
Pretty much the reason I am back in the states / Louisiana at all!
The company that produced these has sold the process and patents to
avaya (of all the companies in the world to sell it to...). They
currently sell them as part of emergency services contracts. I
believe they have greatly enhanced the jitter correction from our
first revisions, however.
Any telephony geeks on this list?
