Skype Dialing Rule Optimizer


The easiest way to set up Enterprise Voice in Skype for Business

Sign in with your Microsoft ID to get started!

Configure Enterprise Voice globally in a few minutes!


Every country in the world has their own set of rules for how telephone numbers can be dialed. It is very difficult for telephony administrators who do not live in those countries to fully understand and implement effective dial plans for their telephony system.

At the same time, configuring Enterprise Voice in Skype for Business is a time-consuming, daunting process for even experienced administrators. Microsoft does not provide much guidance outside of a few specific examples, which leaves administrators guessing how to proceed.

The Skype Optimizer is designed to vastly simplify the work required to create dial plans for 231 countries (alphabetical order/country code order). Using an extensively researched, privately-owned database of each individual country's specific dialing patterns translated into standard "regular expressions", the Skype Optimizer is able to automatically create detailed dial plans for all flavours of Skype for Business.

The end result is a full set of normalization rules, routes, PSTN usages and outbound translation rules that provide administrators with unprecedented control over their Enterprise Voice deployment. Users benefit by being able to dial any number in any way with a higher success ratio that increases overall user satisfaction.

Loads of Features


The Skype Optimizer has many features that make deploying Enterprise Voice a breeze. By utilizing some of the more advanced features of a Skype Optimizer generated script, administrators can create cost-effective and fault-tolerant dial plans that will work in nearly any situation.

Dial rules for every call class

Dial rules for nearly every country can recognize every class of call, including local, national, international, mobile, tollfree, premium and service numbers.

Easy control over dialing authorization

Administrators can easily prevent users from making unauthorized calls. Predefined voice policies can limit members to making only local or national calls, and are set to prevent calls to premium numbers by default.

Local dialing rules for North American numbers

In North America, it's often hard to tell if a number is local or long-distance until actually dialed. The Skype Optimizer takes care of this, ensuring every call succeeds on the first try.

Email notification for dial rule updates

Local dialing areas for North America change frequently. The Skype Optimizer can send email updates with any dial plan changes on a regular basis.

Easily add extension ranges

Add up to 50 internal extension ranges for Skype for Business or external PBXs. The Skype Optimizer will create all the necessary normalization and routing rules. Makes legacy support easy!

Allow selective caller ID blocking

Using unique normalization and routing rules, give users the ability to replace their caller ID with another number on a call-by-call basis.

Least-cost/failover routing

The Skype Optimizer can automatically configure voice policies to provide least-cost routing and failover routing so you can ensure telephony high availability and minimize tolls.

More information

Location-based routing

Keep cross-site audio traffic to a minimum by utilizing features originally intended for toll compliance in countries like India.

Block premium calling for all

Utilizing the built-in Skype for Business Announcement Service in a creative way, the Skype Optimizer can block premium number dialing for all users with custom audio alerting and optional administrator notifications.

Call Park Support

Gives administrators the ability to create call park number ranges in seconds.

Years of experience

All the Enterprise Voice knowledge I've gleaned from years of Lync/Skype for Business deployments is incorporated into this tool. Most of the features here were added to make my own life easier, and I'm happy to share with the world.

About the author

The Hoff

Ken Lasko is the VP of Research & Development for Event Zero who makes analytics and management software for Skype for Business. He's been a Skype for Business MVP for 6 years and counting, and is hoping continued work on the Skype Optimizer is enough to keep him in the MVP circle in perpetuity.

His favorite pastimes include running down beaches in slow-motion, talking to cars, cultivating his chest hair and staring blankly at random people and/or objects.

The Skype Optimizer is the result of countless hours of development (mostly late at night, so any issues can be attributed to lack of sleep), that would have probably taken an actual developer much less time. You see, Ken is NOT a software developer, despite any evidence to the contrary. He learns via Google, and codes via Notepad++, usually with much trial-and-error (emphasis on ERROR).

If you find the Skype Optimizer useful and wish to support future development and hosting costs, please consider donating. It will help me believe that I could someday retire off the riches generated via this tool.
