[FAQ] How to change when the phone dials a number in LYNC / Skype for Business

[SteffenBaierUK]

In a LYNC or Skype for Business environment the Phone receives the Dialplan from the Server via inbound provisioning and will try to translate this.

Polycom does not support all regular expression digit maps and you should verify which ones you can use utilizing the "Polycom® UC Software with Microsoft® Lync® Server and Skype for Business Deployment Guide" 

The reg.1.applyServerDigitMapLocally is usually set to 1.

When set to 1, dialplan normalization rules are downloaded from the Lync Server and processed on the phone.

If 0, dialplan rules are processed by Lync Server. 

• In Lync environment, if the 'reg.1.applyServerDigitMapLocally' is set to '1', the dialplan obtained from the server is applied and the corresponding timeout from the 'dialplan.1.lyncdigitmap.timeout' is being applied
  
  
• In Lync environment, if the 'reg.1.applyServerDigitMapLocally' is set to '1', and 'dialplan.1.lyncdigitmap.timeout' is not set to any value, then the default of '3' secs is being applied
  
  
• In Lync environment, if the 'reg.1.applyServerDigitMapLocally' is set to '0', then 'dialplan.1.digitmap.timeout' is being applied
  
  
• In Lync environment, if the 'reg.1.applyServerDigitMapLocally' is set to '0', and there is no value configured for 'dialplan.1.digitmap.timeout', the value from 'dialplan.1.digitmap.timeout' is considered

The only valid Values to utilize with either the reg.1.dialplan.digitmap.timeout or the dialplan.digitmap.timeout parameters is 1-99.  

0 is an invalid value and is treated like the standard delay of 3.

The maximum Value is 99 seconds.

• Using dialplan.1.lyncdigitmap.timeout="1" it waits 1 second
• Using dialplan.1.lyncdigitmap.timeout="10" it waits 10 seconds

Disabling the LYNC / Skype for Business Dial Plan and manipulating a Number:

dialplan.digitmap="RR+4931420R[6]xxx|x.T"
reg.1.applyServerDigitMapLocally="1"

The above would disable the Dialplan inbound provisioned by the server and automatically add +4931420 prior to any extension which starts with 6 and has a length of 4 digits.

Example:

• The User dials 6999 and the Phone would automatically dial +49314206999

Any other number than 6 and has a length of 4 digits would be send as dialed. More examples can be found => here <=
