I used the DTI-U10 (DTI-24-U10). Got it from GTS Telephone
Inc.(732-323-8620) for $300.00 (reconditioned).
My voice t1 comes into asterisk via the first T100P, and attaches to the
nec t1 via the second T100P using e&m_wink (as a trunk).Then with LCR I
make it add a 9 to the outgoing trunk so asterisk will route it to the
T1.
I grouped the channels that sales calls come into, and I grouped the
channels that go to the nec, so I could use a dial string like:
[sales]
exten => s,1,Playback,transfer|skip ; "Please hold while..."
exten => s,2,Dial,zap/g7/210 ; Ring, Nec sales group
exten => s,3,Hangup
and to ring extensions on the nec I did this:
; nec bridge
exten => _1XX,1,Dial(zap/g7/${EXTEN})
g7 (group7 is the T1 trunk); Extension 210 is a virtual extension set to
ring 5 other nec extensions; and the 1XX will match extensions in the
100 range that are not on the asterisk.
I should get started on the doc's.... didn't realize how far I'd come
till now.
Problems I still have:
1. If someone dials slowly from an nec extension - the nec sends the
first group, asterisk then tells them the number is not in service.
2. IAX2 connection to remote office is still "choppy" occasionally.
Don't know if the pix 501 is getting overwhelmed by the encryption of
voice packets or what?
