Call Server Configuration
Polycom, Inc. 242
If you have special configuration needs and want to modify the dial plan, be aware that some of the default
dial rules are necessary for “normal” operation. Removing or modifying them takes the system out of
compliance with ITU and IEEE standards.
Here are some suggestions and guidelines for modifying the dial plan:
Rule Effect
1 Dial registered endpoints by alias If the dial string is the alias or SIP URI of a registered endpoint, the call
is routed to that endpoint.
2 Dial by conference room ID Otherwise, if the dial string is the dial-in number of a conference room
on the Polycom RealPresence DMA system, the call is routed to that
conference room.
3 Dial by virtual entry queue ID Otherwise, if the dial string is the dial-in number of a virtual entry queue
on the Polycom RealPresence DMA system, the call is routed to that
VEQ.
4 Dial by Lync conference ID Otherwise, if the dial string is the dial-in number of a Lync conference
on the Lync AVMCU, the call is routed to an available Polycom MCU
that supports Lync 2013 and automatically connected to the
corresponding Lync conference on the AVMCU. (If no Polycom MCUs
that support Lync 2013 are available, the conference fails to start).
5 Dial services by prefix Otherwise, if the dial string begins with the configured prefix of a service
(such as an MCU, ISDN gateway, SBC, neighbor gatekeeper, SIP peer
proxy, or simplified ISDN dialing service) the call is routed to that
service.
Note: For a SIP peer, the dial string must either include the protocol or
consist of only the prefix and user name (no @domain). For instance, if
the SIP peer’s prefix is 123, the dial string for a call to
alice@polycom.com must be one of the following:
sip:123alice@polycom.com
123alice
6 Dial external networks by H.323
URL, email ID, or SIP URI
Otherwise, if the address is an external address, the call is routed to
that external address (H.323 calls use the designated SBC for the
originating site to reach addresses outside the enterprise network; see
Edit Site Dialog Box on page 285).
Examples of external addresses:
H323:johnsmith@someothercompany.com
sip:johnsmith@someothercompany.com
7 Dial endpoints by IP address Otherwise, if the address is an IP address, the call is routed to that IP
address (H.323 calls use the designated SBC for the originating site to
reach addresses outside the enterprise network).
Examples of IP addresses:
1.2.3.4
1.2.3.4##abc
sip:abc@1.2.3.4
sip:1.2.3.4@mycompany.com
