Dial Plan on IP321



We have Polycom 321 phones deployed in the UK and have an issue where if a line is siezed before dialling (i.e. user picks up handset and then dials number) the call is attempted after 3 digits.


What parameter is required in the config file to change this to a time out of say 5 seconds?


Also, I have been unable to locate the parameter to limit numbers of calls per line on the same handset.

You need to modify the dialpal.digitmap parameter. Look in the site.cfg template file.


To limit the calls per line, check out call.calls.perLineKey .

What does the 3|3|3|3|3|3 digit timeout mean?


Is it 3 seconds timout and if so why repeated 6 times?

Also, my actual digit map is set as [2-9]11|0T|011xxx.T|[0-1][2-9]xxxxxxxxx|[2-9]xxxxxxxxx|[2-9]xxxT


Basically, I want to be able to dial a 4 digit extension number or an 11 digit local / national number or in fact an international number in full and then after a timeout of 3 seconds for the phone to send the call.

Hello icsnettech,


Welcome to the Polycom Support Community.


The Admin Guide and Software for your Phone can be found => here <=


Quote from the UCS 3.3.0 Admin Guide:


Page A - 38



string of positive integers separated by "|"

Timeout in seconds for each segment of digit map.Note: If there are more digit maps than timeout values, the default value of 3 will be used.If there are more timeout values than digit maps, the extra timeout values are ignored.


The Amount of 3| Entries depends on the amount of | seperated sequences in the dialplan.digitmap


Both values can be changed via the Web Interface or a Configuration File loaded from a provisioning server.


The UCS Admin Guide explains the digitmap setup and the Phones come with a US Dialplan from Factory.






[9]99 = 999 is a valid rule

*xx = Two digits preceded by an asterisk is valid (used for feature codes)

[0]xxxxxxxxxx = UK National numbers i.e. 11 digits first digit being a 0.

[4]xxx = Your internal extention range i.e. 4 digit number starting with a 4.
