What we do

SIP business phones — desk to pocket.

Hosted Voice is SIP-based business phone service. We provision the endpoints — desk phones, desktop and browser softphones, and mobile apps — and register each one over TLS so the same extension follows a person wherever they work. We handle number provisioning and DIDs, and we plan E911 per location so an emergency call resolves to the right address.

We deliver it on an open-source stack we run ourselves or on a partner platform when that fits better — and we’re able to quote and integrate with the platforms we’re partnered with. Either way, BYOD and BYOC are on the table, and the everyday call features — transfer, hunt groups, voicemail — are configured to match how you actually route calls, not a vendor default.

What we deliver

Endpoints, numbers, and the features around them.

Desk phones & softphones

Physical handsets, desktop softphones, and browser clients — provisioned, registered, and templated so a new extension is minutes, not a ticket queue.

Mobile apps & BYOD

The same extension on a phone in a pocket — mobile apps and bring-your-own-device so people carry one number, not two.

Number provisioning & DIDs

New DIDs where you need them and a clean plan for the numbers you already own — we provision, assign, and document them.

SIP registration & signalling

SIP registration for every endpoint over TLS, with SRTP on the media path — signalling we can read in a trace when something looks off.

E911 considerations

Emergency calling that resolves to the right location — we work through E911 registration and dispatchable-location handling per site, not as an afterthought.

Call features

Transfer, hunt groups, and voicemail — the everyday features a team leans on, configured to match how you actually route calls.

Problems we solve

If any of these sound familiar, we should talk.

You're paying per seat for a hosted phone service and nobody can tell you where the numbers actually live.
Staff are handing out personal mobile numbers because the desk phone doesn't follow them off-site.
E911 was never set up — an emergency call would resolve to the wrong address, or nowhere at all.
Endpoints are a mix of desk phones, apps, and half-configured softphones with no consistent registration.
You want the flexibility of a partner platform but need someone who can read the SIP trace when it breaks.
