looking back at the messages file for the past 2 days. it
just hanged on totally different events none of which related
to Local channels.

as far as the PRI not hearing early media issue. here's the
excerpt from the messages file after "pri debug on" command:

***********************************

i used the same SIP station to dial the same 800 number
on both versions (1.8.3.2 & 1.6.2.17). the output are
pretty much identical except on 1.8.3.2, after the
"PROGRESS with cause code 127..." message. i would hear
nothing until the other side timed out & hang up, whereas on
1.6.2.17. i got the "DAHDI/... is making progress passing it to SIP..."
message and can hear the early media from the other side.

> For Now 1.8.3..2 is very bad.

agreed...
