[Asterisk-Users] 7960 MGCP dialtone problems, part 1 [long]

[John S.]

Hi all,

I've been trying on and off again for several months to get my 7960 
(MGCP 5.3) working with * with no success.  As you know, working MGCP 
configs for non-ATA Ciscos seem to be very hard to come by.  I'm not 
shooting for the moon here, just trying to get dialtone at the moment.

The problem I'd like to focus on today: I only get dialtone when I go 
off-hook (via the Speaker button, if it matters) maybe once every 3 
tries.  If it fails, or after I've successfully gotten the dialtone 
once, the phone will not get it again until it has been power-cycled.

This is a failed attempt below.  Config files are at the bottom.  See my 
next message for a successful attempt.
