[asterisk-users] Asterisk analog DID with Adit 600

[Dave Fullerton]

Hello All,

I'm trying to connect Asterisk to an Executone phone system with an 
analog DID card and I'm hoping someone can help me figure out what I'm 
doing wrong. The Executone DID card provides battery to the telco, when 
the telco wishes to dial a DID it goes off-hook, waits for a wink from 
the Executone and then dials the last three digits on the number with 
pulse (as opposed to DTMF) signalling.

What I've done is purchase an Adit 600 with an FXO card. I've set the 
Adit T1 controller to use E&M signalling and the FXO card to use DPT 
signalling. I've set asterisk to use E&M in both dahdi/system.conf and 
chan_dahdi.conf.

If I dial the port connected to the DID card it goes off hook but when 
the Executone winks Asterisk or the Adit thinks the remote side has hung 
up and terminates the call.

I've tried using E&M wink, featd, and featb signalling in 
chan_dahdi.conf, set hanguponpolarityswitch=no, and tried loop start 
signalling for the heck of it and that didn't work either.

Does anyone have any suggestions of additional things I could try?

Thanks in advance,

-Dave
