make calls between two servers using Digium card

[gattaba]

Hello, I have two servers with this configuration:
server 1:
Goautodial 2.1
version 2.4-309a
build:110430-1642
asterisk 1.4.39.1
digium card : Wildcard TE410P configured in chan_dahdi.conf "signalling=pri_net"
server 2:
Goautodial 2.0
VERSION: 2.2.1-237
BUILD: 100510-2015
asterisk-1.4.27.1-1
digium card: Wildcard TE122 configured in chan_dahdi.conf "signalling=pri_cpe"

I would like to generate multiple calls from server 1 to server 2 via the cable connected between the two cards to simulate a call center.
I am a beginner is that someone can tell me the procedure to follow step by step.
thank you
excuse me I'm going through google translation

it would make more sense to connect the two machines with an ethernet cable. in which case one would be set up as a "carrier" to the other which would consider it a "remote agent" or an extension.
