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 the Merlin or Genie family of 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.
