Dial and Answer Route Settings in Programs
Dial Route and Answer Route tags allow you to associate a POTS Config with a particular
incoming audio stream from either Tieline or non-Tieline codecs.
In principle, this operates similarly to how audio ports are used to route multiple audio streams over
IP. Selecting different IP audio port numbers allows users to define which incoming IP audio stream
is routed to a specific answering audio stream configuration on the codec. This ensures inbound
calls from multiple codecs can be consistently routed to the same answering audio streams, and
therefore the same inputs and outputs.
This is not necessary in simple point-to-point POTS audio stream configurations, however it is very
useful in multiple audio stream codecs which support POTS connections. When dialing Tieline to
Tieline over POTS using ViA, or Merlin and Genie codecs, you can configure a Dial Route in the
dialing codec's program and a corresponding Answer Route in the answering codec's program. This
will ensure a particular audio stream is routed between two codecs consistently.
Answer Routes for Non-Tieline POTS Codecs
In some situations you may receive a call from a non-Tieline POTS codec which doesn't support
Dial Route tags. In this situation you can still specify the audio stream Route on the answering
codec using Config 1 or 2 in POTS Answer. You can also select the default algorithm.
For example, if a call from a non-Tieline codec is received via POTS Module 1 (i.e. no Dial Route
has been specified in the dialing codec):
1. Open the HTML5 Toolbox Web-GUI and click Transport and then POTS Answer to view
and configure POTS answering site settings.
2. Click the Edit button to configure settings.
3. Select an answering Route for this POTS module in one of the two Configs available in the
POTS Answer panel, e.g. Route1, then select the default Encoding algorithm Other
(Note: Other is used for connecting to Comrex POTS codecs).
