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
A, you must first configure a SIP trunk in Sipelia™
Server to connect to SIP Server
A. Then you must define a dial plan to route the call from Sipelia™ Server to SIP Server
A. 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 plans.
