Our customers are using a wide array of broadband internet connections.
You need to consider bandwidth requirements. Top Line Communications uses G.711 signaling which requires approximately 100 kbs of bandwidth. It is mportant to understand your present bandwidth requirements before adding SIP Trunks. If your organizations downloads and uploads large files, documents, video or music you may consider obtaining a second internet connection dedicated for SIP.

Although your local phone or cable provider may tell you SIP/VoIP will not work on their broadband service. This is far from the truth. In fact many local service providers are using broadband phone service and not passing the savings to the customer.

SIP works on DSL, ADSL, SDSL, Cable, T-1, dedicated ethernet, and VPN.

Typically we do not offer broadband service, however if you are having difficulty finding a relyable broadband service, please let us know if we can assist.
