[asterisk-users] Integrating Asterisk with a Panasonic D500 using MFC/R2

[Carlos Chavez]

	I am trying to get my Asterisk server to talk to a Panasonic D500 PBX
using an E1 connection.  The card for the Panasonic uses MFC/R2 and I
have installed Unicall.  Calls from the Asterisk server to the Panasonic
go through without a hitch and I can call any extension I want.  The
problem is that I cannot get any calls from the Panasonic.  I have the
following log from a call:

Aug  9 00:27:13 WARNING[14641] chan_unicall.c: Unicall/1 event Protocol
failure

	According to the Panasonic tech person the problem is that Asterisk
insists on getting the Group C request for a callerid.  I tried to
disable callerid in unicall.conf but the result was always the same.  I
have mx,10,4 so after I get the first four digits I get the protocol
error.  I know many people have integrated with PRI, but the card on the
panasonic does not support that.
