SIP trunk services for business phone systems

A SIP trunk delivers phone lines over your internet connection straight into your PBX. Instead of adding copper lines one by one, you add channels — the number of calls that can run at the same time — and route inbound numbers to the right team.

What is included

  • SIP trunk configuration on Yeastar, Grandstream, Asterisk-based and other SIP PBX systems.
  • Channel sizing based on your busiest hour.
  • Inbound routing of each DID number to extensions, ring groups, IVR or queues.
  • Failover routing so inbound calls still reach you if a link fails.
  • Outbound restrictions and alerts to reduce toll-fraud risk.

Who it is for

Offices replacing analog lines, multi-branch companies sharing one set of trunks, call centres that need many channels, and hybrid teams. If you still have existing landlines, FXO gateways can connect them to the same IP PBX.

FAQ

Questions about SIP Trunk Services

Can I connect a SIP trunk to my existing PBX?

Yes, if your PBX supports SIP. We configure the trunk, codecs and routes on your system.

How many SIP channels do I need?

Enough for your busiest hour of outside calls. We help you estimate this from your call pattern and leave room for growth.

Can SIP trunks work for remote or hybrid teams?

Yes. Calls arrive at the PBX and can ring extensions wherever staff log in.

What happens if the internet goes down?

We can set up failover routing so inbound calls are forwarded to another number or line during an outage.
