Common questions

I can't find the guide for my phone system. What do I do?

Call (866) 740-7771 or use the contact form. Tell us your system, Sangoma or Wildix, and what you're trying to do, and we'll send the right document or walk you through it directly.

How do I request a change to my phone system?

Moves, adds and changes are unlimited on Hiscall cloud agreements. Call the number above or submit a request through the contact form, and a technician will make the change, usually the same day.

Who do I call for a billing question?

The same number handles billing, service and technical questions: (866) 740-7771. You'll reach a Hiscall employee, not an automated system or an outsourced call center.

Do you have manuals for older equipment that isn't listed here?

Likely yes. This page covers the two most common systems we support. If your equipment isn't listed, call us directly and we'll get you the right document.

Can't find what you're looking for?

A Hiscall employee answers the phone, not a queue. Call us and we'll get you the document, the answer, or a technician, whichever the situation actually needs.
