VOIP SIP T1 Line

VOIP SIP T1 (session initiation protocol) is the state-of-the-art progression of voice technology. With VOIP SIP T1, modern IP PBXs can now connect directly to the public switched telephone network (PSTN), without the added cost of a PRI card and the inefficiencies of protocol conversions. VOIP SIP T1 can be obtained as voice only, or included as a component of a dynamic integrated T1 package. Two relatively new features which are often available with SIP are virtual DIDs (direct inward dial numbers), including international DIDs, and voice packet compression.

Compression enables SIP T1s to include up to twice as many voice lines without loss of call quality. Virtual DIDs enable companies to appear to have a local presence in other locations of the US , by providing local phone numbers for these locations. Several SIP packages can include international virtual DIDs as well. With an international DID, a company in the US can have a phone number that is local to another location of the world. When that number is called from that location, it rings to the company?s US location like it is a local call. With international virtual DIDs, companies located in the US can appear to a have local presences in many other countries of the world.

Another advantage of SIP T1 is that is can be available to any location that it is available over a private bandwidth circuit, or a pubic (internet) circuit. The major advantage SIP over the private circuit of a SIP provider is that the provider can and will ensure priority of voice packets as they travel across their network, until those packets reach the PSTN. This results in perfect voice quality. The major advantage of SIP over the internet is that locations that traditionally could not obtain voice T1 by providers other than their local telephone company, will now have extremely cost effective alternatives, if they are willing to accept that voice quality may not be equal to voice traffic carried over a private network. SIP is available over either T1 or DS3.
