POTS Lines

POTS (Plain old telephone service), is the voice-grade telephone service that remains the basic form of small business service connection to the PSTN (public switched telephone network) in most parts of the world. It is also commonly used for internet access via a dial-up modem, DSL, fax, credit card terminals, and alarm lines.


An ISDN PRI (Primary Rate Interface) is a dedicated voice circuit consisting of 23 B-channels and one D-channel and is delivered via a T1 facility. For many businesses, an ISDN PRI is far more cost effective than deploying POTS service on per line basis and a PRI offers lower usage rates. Additionally, all PRIs include support for DID (Direct Inward Dialing) and toll-free numbers. A PRI is a standard deployment that integrates with most every PBX in the marketplace today.


SIP (Session Initiation Protocol) trunks provide access to the telephone network via VoIP (Voice over Internet Protocol). SIP provides all of the features of a PRI and many additional advantages including voice / data convergence, scalability, and automatic call rerouting in disaster recovery scenarios. SIP trunks are commonly deployed with IP-PBX devices which are either hosted by a third party or premise based at a business location.

Hosted VoIP

Hosted VoIP is a voice service that is provided by a carrier whereby the PBX hardware resides on their network rather than at the customer’s premise. Hosted VoIP is a perfect solution for a small to medium business seeking the advantages of VoIP without the the capital expenditure required for premise based hardware.
