codecs can also be configured to accept 2 ISDN calls from non-Tieline codecs and would use
similar settings).
In the following example we will configure two incoming sessionless ISDN audio stream
connections (Note: Genie Distribution and Merlin PLUS support up to 4 sessionless ISDN audio
streams/connections/configs using 2 ISDN modules and 4 B channels). If you want 2 incoming
mono ISDN calls to use inputs/outputs 1 and 2, then use answering audio stream connections 1
and 2 in a 2 x mono peer-to-peer program.
So let's get started. There are 2 or 3 steps to ensure this is configured correctly, depending on
whether you want specific incoming calls to always use the same B channels and codec outputs or
not.
Step 1: Configure the Answer Route for the two ISDN Audio Stream
answering connections in the codec program.
Setup two ISDN audio stream answering connections in your program and use the Answer Route
setting in the program wizard (as displayed in the following image):
You can use any Answer Route, for example Route 1 for ISDN Audio Stream 1 and Route 2 for
ISDN Audio Stream 2. The Answer Route number doesn't have to match the audio stream number
because the route you select will be used by the incoming ISDN call. This is similar to how an
"extension number" is used to route a phone call.
Step 2: Configure the ISDN Module to accept two sessionless ISDN calls.
This can be configured via Settings > Modules or use the Toolbox Web-GUI via Transport > ISDN
Answer Modules.
1. Select Config 1 and Sessionless Only and Route 1. Select your preferred algorithm, then
click Save. This means that Module 1 B channel 1 will answer a sessionless ISDN call
using these settings.
