User Dial Plan Setting
The IP Phones have a parameter for configuring a dial plan that distinguishes between calling a
PSTN number and an Internet URL.
This parameter is “sip user parameter dial plan”. Using the configuration files, an
Administrator can configure a dial plan (i.e., 6xx|8xxxx|9xxxxxxx) that the phone checks before
sending the SIP packet. If for example, the number that was dialed was 645, the phone checks
the dial plan and matches the number to the dial plan (6xx in the example above), before sending
out the SIP packet. The SIP packet header indicates user=ip (i.e., “To:
<sip:[email protected]:10060;user=ip>“). If the number that was dialed was 9,456-2345, the
phone matches the number to the dial plan (9xxxxxxx in the example above), before sending out
the SIP packet. The SIP packet header in this case indicates user=phone (i.e., “To:
<sip:94562345:10060;user=phone>“).
An Administrator can use the following parameter in the configuration files for this feature:
•
sip user parameter dial plan
When you enter a value for this parameter in the configuration files, the phone performs in the
following manner:
Note: Entering a dial plan value for this parameter enables this feature.
Entering no value for this parameter in the configuration files, disables
this feature.
WHEN THEN
the SIP phone calls a PSTN phone
number, the network uses the “sip user parameter dial plan” value to connect the call to the
far-end destination on the PSTN (User = phone).
For example, the network would use the parameter if the following dial plan was
configured:
sip user parameter dial plan: 6xx | 8xxx
This indicates the destination phone is on the PSTN network and so the
parameter is used.
the SIP phone calls a SIP phone, the network disregards the “sip user parameter dial plan” value and connects the
SIP phone to the far-end SIP destination (User = IP).
For example, the network would not use the parameter if the following dial plan
was configured:
sip user parameter dial plan: 8xxx
This indicates the destination phone is on an IP network and so the parameter is
not used.
