Common Questions and Issues


Dial ∞+394. Look at the display and verify the display says STATION DEFAULTED. This will reset the phone to the factory settings.


From the administrative phone only, dial ∞+9800 (or Ⓧ+9800) and follow prompts.


From the phone, dial 2500 and press * once the prompt start. Follow the prompts, including inputing the extension of the phone whose greeting you wish to change.


From the phone, press the message key and follow the prompts. If you’re calling in from somewhere else, dial the main number and as soon as the greeting starts dial *. Follow the prompts.


First, default the phone. If this does not work, try switching out the handset or handset cord. If this still does not work, then seek further assistance.


Look at the display to ensure that it displays your extension number and the date & time; if the display is blank, then there is no power going to the phone. Test to see that if you can speak with another extension; if you can, then this indicates that the system is working, but the outside service is not working. If this still does not work, then seek further assistance.

Happy PeAk Communications Systems Customers!

Thanks Steve!

The guys did a great job with the install. It looks really nice and they left the place really clean. You’d never know there had been work done. They took a few minutes to walk us through the basics and answered the questions we had.

Great team! Kudos to them!!

Thank you for the great customer service!

I have been working with Mitel (& PCS) for almost two years now. I did not have any training when I began using the system at a new job. The system is quite easy to learn and has so many great options such as voicemail to your email. Even if you accidently delete the message from your phone you can replay it through your computer. I love the instant messaging. You can be on the phone with a client and message a co-worker with a question at the same time. I believe this system saves me precious time on a daily basis. I have worked with several phone systems in my time but this one has to be by far the greatest.

We have had the pleasure of working with Peak Communication Systems on several occasions now for our telephone system and cabling needs.

When we moved into our new offices in February of 2016. Steve Rubin and his technicians wired all of our telephone lines and our internet connections. His price that he charged us for this service was more than reasonable. He was prompt, courteous and did a wonderful job. He even came out in the middle of a blizzard to finish the job.

We would highly recommend Peak Communication Systems for any of your telephone needs.

Thank you!
