[Asterisk-Users] iconnect quality?

[Jim Archer]

Ok!  When I use the 7777 prefix and I allow gsm it does work!  And the 
quality is fine.

There are two problems we're having now.

1 - From watching the udp fly by, it seems that iconnect does not know when 
we hang up.  For example, if I call a voice mail and it starts giving me 
its speal and I hang up, iconnect stays connected until the VM hangs up at 
its end.

Next, if we try to call out via iconnect from a sip client extension (like 
a windows soft phone) all we hear is horrible noise.

Has anyone else had these issues?

Jim
