SIP Trunking & Number Porting
Keep your numbers. Lose the copper bill.
- From $18 per channel / mo
- Design in 5–10 business days
- Carrier-neutral sourcing
If your PBX still does its job, you do not need to replace it to stop paying for copper. SIP trunking moves the outside lines onto your data circuit and typically cuts line costs by half.
We size channels against real call data rather than guesswork, configure failover and E911, and manage the porting paperwork with both carriers. Your numbers, your call flows, no unplanned silence.

FAQ
SIP Trunking questions, answered.
Will our numbers change?
No. Porting keeps your existing numbers. The only change is the path the calls take, and we schedule that cutover when your business is quiet.
How many channels do we need?
A common starting point is one channel per 3–4 staff, adjusted for peak concurrent calls. We pull 30 days of call detail records to size it properly.
Does SIP work with our old PBX?
Most business PBXs from the last 20 years support SIP with a licence or gateway. We confirm compatibility during the audit before quoting.
What about fax and alarm lines?
Fax works over a T.38-capable trunk. Alarm, elevator and fire lines need a dedicated POTS replacement solution — we handle those separately.
