[asterisk-users] Dialtone when automatically picking up.

[Peter Hessler]

I'm in the process of setting up a 'phone tree', and are running into 
some problems.  My goal is for users to dial a phone number, the 
asterisk system picks it up, plays the greeting, and users can type 
whatever they want into the system.

What actually happens is users dial the phone number, asterisk picks up 
and additionally goes off-hook on another line, plays the greeting and 
the dialtone over the incoming channel, drops some keypresses (seems to 
only acknowledge the 2nd digit of any length key press), plays 
'invalid', loops back to the beginning (re-plays the message, etc) and 
now behaves normally (no dial tone, accepts all keypresses, etc).  When 
you use a local phone to dial out-in, you can call 3 digit numbers 
(which are dialed 'underneath' asterisk), but if you aren't using a local 
SIP client, then the system does not send the keypresses to the outside 
line.  If the dialplan is to Dial() a number, everything works the way I 
expect.

I essentially copied my dialplan out of the Asterisk: TFOT book, and 
everything seems sane.  I've included the relevant parts of my config, 
and a verbose watch of the call below.  More information is available, 
please let me know.

The hardware is a Sangoma Remora+Shark card, with inbound POTS/PSTN 
analog lines connected to FXO cards.  My testing methodology is both 
using a SIP client to dial the inbound line (therefore going outbound 
to the Phone Company, then back in), and by using a cell phone to dial 
in.

Asterisk 1.2.22 on CentOS 5.0.  kernel 2.6.18-8.el5.  Zaptel drivers are
at 1.4.4, WANPIPE drivers are at 2.3.4-12.
