SIP Trunk
IP trunking that replaces legacy TDM lines with burstable channels and real savings.
Overview
SIP trunking connects your existing PBX or cloud telephony platform to the public network over IP. Channels burst when call volume spikes, numbers are portable across sites, and per-minute costs drop sharply against TDM. We handle interoperability testing with your PBX and the number porting paperwork.
What you get
- Burstable concurrent call channels
- Geographic redundancy across POPs
- Number portability from existing lines
- Works with on-premises PBX or cloud platforms
- Significant per-minute cost reduction
Typically bought by
Any organisation still paying for PRI or analogue trunks.
