    • WHAT IS AN LOA AND WHY DO I NEED ONE?

      An LOA or Letter of Authorization is a document that allows your phone/VoIP vendor to request your numbers on your behalf.  The LOA also allows your vendor to talk to your provider to help with service issues, contract questions or porting.  The LOA is filled out and signed by the person that is Authorized on your carrier account and then given to your phone/VoIP provider.

    • WHAT DOES PORTING A NUMBER MEAN?

      When you port your number you are moving your telephone number from one provider to another provider (i.e. – moving from CenturyLink to Comcast).

    • CAN I MAKE PHONE CALLS WITH VOIP IF I LOSE POWER?

      Losing power can cause your Internet connection to go down.  If this happens you will not be able to make calls unless you are equipped with a backup UPS, which could power the connection for a limited short duration (enough time to finish calls).  One benefit to using SIP Trunks or Hosted PBX with DB Networks is that if you lose power or Internet connectivity due to the carrier being down, you can automatically have a failover option in place that will immediately start forwarding calls to a number specified by you (cell number, etc.).

    • WHAT KIND OF INTERNET CONNECTION DO I NEED FOR VOIP?

      You will need a broadband Internet connection such as DSL, Cable or others (T1, Wireless, etc.).

    • WHAT IS VOIP?

      VoIP stands for voice over Internet protocol.  VoIP is a technology that allows your voice to be sent over the Internet.  VoIP Services can be used with your PBX (on-premise or Cloud)
