A dial plan is a collection of rules that defines how calls are
routed locally or between two SIP trunks. Dial plans
ensure that calls are routed and rerouted correctly, and they also allow
administrators to block calls to certain geographic locations or ensure the
privacy of the callers.
A dial plan defines one or multiple rules to specify the following:
- How calls can reach SIP extensions that reside on other SIP servers.
- How calls coming from other SIP servers can reach SIP extensions that reside on Sipelia Server.
- How calls can be forwarded even when they remain local to Sipelia Server.
- How Sipelia Server can modify dialing
information such as source or destination SIP extensions during call routing.
For example, if a SIP extension registered to Sipelia Server
needs to call an extension that
resides on SIP Server
, you must first configure a
in Sipelia Server
to connect to SIP Server
. Then you must define a dial plan to route
the call from Sipelia Server
to SIP Server
. In Sipelia™
, dial plans can also be used to route local calls,
that is, calls that must remain in Sipelia Server
NOTE: Dial plans also need to be
configured on SIP Server
A to route calls from and to
Sipelia Server. Refer to the
documentation provided by the manufacturer of SIP Server
A for information on how to configure dial
