Welcome to CallGroup

Streamlined on-call. Stress-free post-call.

Step 1: Create your schedule

Maintain your call schedule with our simple to use website.

Step 2: Publish your number

Each group receives a dedicated number.

Step 3: Calls are auto-routed

Incoming calls are routed only to the person on call.

Step 4: Answer the call

Answer the incoming call from your preferred device.


CallGroup replaces outdated paging and locating services with an intuitive, visual system. Our web-based calendar allows group members to make changes to the call schedule knowing that incoming calls will be redirected in real time.

Each group is provided with their own unique telephone number from which incoming calls are directed and then auto-routed to the on-call individual on their desired device.

Designed with physicians in mind, the product is ideal for any profession whose members may need to be reached at all hours, such as plumbers, locksmiths or real estate agents.



Our Story


Our team

CallGroup was formed when its founders, Shamus Rask and Joe Duong, identified a need for a practical way for individuals working on call to manage their on-call hours and achieve a better work-life balance. Shamus and Joe's complementary backgrounds in technology and computer programming led to a natural partnership.



Shamus chose the entrepreneurial path as a way to create a more balanced family life. He has a B.Sc. in Electrical Engineering from Queen's University, is a licensed Professional Engineer and has worked for a number of large companies, including Bell and Alcatel-Lucent. An accomplished juggler and unicyclist, he enjoys spending his rare off-hours with his family, sharing his love of outdoor activities with his two young children.



Joe has a degree in Physics with a minor in Computer Science from the University of Waterloo. He has worked as a programmer for over 15 years and started his own company because of the flexibility and freedom that being self-employed offers. Joe loves to create fun new things and has many ideas for future projects. A self-professed jock, when Joe finds himself with some spare time he can usually be found playing some sort of sport.

Redirect Options

Each user can add up to 3 phone numbers (e.g. mobile, home, pager, office extension) to their user profile. The user can change these numbers at any time.

Ring on Multiple Devices

Users can choose whether they want their 3 phone numbers to ring simultaneously or sequentially.

Voicemail Smart

For any phone number, a user can select whether the system should ignore their voicemail if it answers.

Real-Time Editing

Any of these options can be modified at any point to change how the next incoming call is directed.

Share Digitally

An on-call group can create and share a read-only link to their on-call calendar, eliminating the need to share paper copies, as the link will immediately reflect all updates.

Privacy Protection

Never share your personal number again, only your CallGroup number.


Don't just take our word for it. Listen to what real customers have to say.

"CallGroup works so well that I've forgotten we use it. I have never received a call outside of my on-call days. I can still remember residency when calls would come even days later.

The CallGroup system is excellent."

Dr. Isabel Li

"I have been a user of CallGroup for 3 years [and] as you've stated and my life is GREAT! I used to get calls from [the in-patient] floor all the time as it was hard for the nurses to know who was on-call and when. Now, they all call one number and it ALWAYS goes to the correct person.

I have never had an inappropriate call since using CallGroup. There has never been any complaint that nursing could not find my number. My family is also very happy that when I [finish on-call], I am not worried about being called in the middle of the night for [in-patients] when someone else is actually on-call.

Thank you for inventing such a wonderful product! It should be used by all ON-CALL physicians as it makes life so much easier!!"

Dr. Brian Morris

"CallGroup has been the most efficient, effective way for my patients and colleagues to connect with me that I have ever experienced. During the years that I have used this system, I have experienced no system downtime, no system failures - it has been faultless. Changing schedules is easy, finding out which of my colleagues is on call is easy, the whole setup is easy.

Using CallGroup has really simplified my life. I have had the same message on my mobile phone for two years now, ending with "If I don't call you back promptly, simply dial (my CallGroup number) and my colleague on call will speak to you." Wow. That is so easy. My patients appreciate that they just need one number to call."
