Guys:
I routinely run multiple phones over our satellite system (I'm the VP of
Network Services at SDN Global, a satellite bandwidth provider located in
Charlotte NC, US).
Just last week I went to West Palm Beach, FL US and turned up a 10 phone
emergency call center, complete with ACD queues for an insurance company.
We were able to run all ten phones (Cisco 7960Gs, SIP) on G.729 codecs back
to my * server in Charlotte NC US. No special settings were required on *
or the phones.
The satellite system *must* support *REAL* QoS and must have jitter <
~100ms. Traditional satellite systems have *lots* more jitter than that.
The actual latency _doesn't matter_ as long as the jitter is steady. We are
even doing 'double-hop' phone calls successfully, where the latency is
double the normal latency.
Anyone that wants more detailed info contact me off-list.
Out of sheer curisity, the delay itself doesn't make the conversation 'bad' (meaning, walkie-talkie/roger-and-over-like ?)
The codec itself should introduce some dozens of ms, but the satellite, is not at least 300ms one way or something like that ? adding the codecs, and the jitter buffers and etc..I wonder how good/bad is it ?
