Application Configuration File
The configuration file sip.cfg contains SIP protocol and core configuration
settings that would typically apply to an entire installation and must be set
before the phones will be operational, unless changed through the local web
server interface or local menu settings on the phone.
The important parameters for the Polycom VVX 1500 C phone include:
• Dial Map <dialmap/>
• Feature <feature/>—To enable call lists, call recording, corporate
directory, and digital picture frame.
• DNS Cache <dns/>—To enable server redundancy.
Dial Map <dialmap/>
A digit map is defined either by a “string” or by a list of strings. Each string in
the list is an alternative numbering scheme, specified either as a set of digits or
timers, or as an expression over which the gateway will attempt to find a
shortest possible match.
Edit the digit map according to your Cisco Unified Communications Manager
call routing. For example:
where:
•x equals any digit (for example, 3xxx means match anything starting with
3 and is 4 digits long). The x is case sensitive.
•T refers to any standard number of digits according to the North American
Numbering Plan (NANP). The T is case sensitive.
•R (not shown) indicates that certain matched strings are replaced. For
example,
R9RRxxxxxxx
means remove 9 at the beginning of the dialed
number. If a customer dials 914539400, the first 9 is removed when the call
is placed. For example,
RR604Rxxxxxxx
means prepend 604 to all 7 digit
numbers. If a customer dials 4539400, 604 is added to the front of the
number, so a call to 6044539400 is placed. The R is case sensitive.
Note
A per-registration digit map is also supported.
