14 Dial Plan
14.1 Dialing Rules
As a user dials digits on a phone, the server collects the digits, one at a time. How does
it know when it should wait for more digits (because the user is dialing slowly) or when it
should take the digits it has and try to make a call with them?
Dialing Rules specify to the Allworx server what digit sequences are valid for dialing out
on the public phone network.
Enhanced external dialing rules enable matching specific dialing sequences and then
deleting, inserting, and/or appending digit strings to those numbers before sending the
dial string to any SIP Gateway, SIP proxy, T1/PRI Digital Line, or CO line. This flexible
dialing enables users, including international partners, to program the dialing behavior of
the Allworx system to match specific business needs such as:
• The server can import and export the dial plan information. This includes Internal
Dial Plan, Emergency, and External Dialing Rules. To support the dial plan
information, users can also import and export the Service Groups.
• New “Send digits as dialed” selection for FXO Lines, Digital Lines, and SIP
Gateways. The enabled default is “Send digits as dialed” for everything except
SIP Proxies to preserve legacy default behavior
Examples:
When dialing a local number, users do not normally dial 1 and the area code. So, the
system collects the first 7-digits dialed, and then tries to make the call. The server should
not be waiting for more digits.
When dialing a long distance number, users normally dial 1 plus the area code, and then
the 7-digit local number. The server recognizes this case distinctly from the local number
case, and knows to collect all 11 digits before trying to make the call.
In addition, some local calling areas require dialing an area code without the 1 prefix in
order to properly dial some numbers. This implies that these rules may vary depending
on the local calling area with an installed Allworx server.
