Use SIP services with your existing or new phone system to reduce telephone line costs and gain flexibility.

  • If you have an IP-enabled phone system, you're ready to use SIP right now.
  • If you have a traditional phone system, you'll need to purchase a gateway, also known as an integrated access device. The gateway you'll need depends on your phone system, so please contact us for help.

And remember that all of our SIP products come with our free meeting services.

SIP Trunks

SIP trunks provide one concurrent call and include inbound usage. Telephone numbers and outbound calling are extra. The minimum order is 4 SIP trunks.

SIP DID Packages

Our SIP DID packages include unlimited concurrent calls and unlimited inbound calls. With this Appia exclusive, you'll never have too many or too few phone lines, and your callers won't hear busy signals, even at peak calling times. Order packages based on the number of phones numbers (DIDs) and minutes you need. Click to see the features included.

Auto-Attendant for Fail-Over

Should your PBX fail, you can fail over to another PBX, which is expensive, or to a phone number, which is inefficient. Or you can fail over to our auto-attendant in the Cloud.

Failing over to the Cloud provides seamless service to your callers. There are two versions of the auto-attendant: Basic and Advanced. Click to see the differences between the two. Both include a company directory and a tool that enables you to self-administer the auto-attendant.
