SIP technology explained - What is SIP?

Save money on your voice calls without sacrificing call quality

What is SIP?

SIP (session initiation protocol) technology lets you run your voice calls over your data connection. Using a BTnet leased line, this can help your business save money without sacrificing call quality. SIP can offer:

Savings on calls compared to your standard telephone bills
Your standard phone line is replaced by the IP network. VoIP call rates are usually lower than traditional equivalents.

Flexibility in how you can use your numbers
With SIP you can move existing or have new numbers outside of your local exchange area.

Lower-cost business continuity options
You could route your VoIP calls over your existing IP network saving money on costly call-forwarding.
