Voice for Contact Centres

Calls that get answered

Answer rates live and die on the route. Every call carries your calling number end to end, so the destination network sees a real number, more calls are picked up and fewer are flagged.

Capacity sized to your peaks

Each account has its own call-rate and channel allowance, set for your operation and raised on request ahead of a campaign. It is never shared with another customer's traffic.

Numbers where your customers are

Local and national numbers in 96 countries for inbound queues and local presence on outbound, delivered into your platform over SIP and moved between campaigns from the portal.

Questions

Frequently asked

Can you handle our campaign peaks?

Yes. Each account has its own call-rate and channel allowance sized to your operation. Tell us the peak hours and the destinations before a campaign starts and we raise the allowance ahead of it. It is never shared with another customer's traffic.

Is our caller ID delivered as we send it?

Yes. Every route carries your calling number end to end. It is not stripped or substituted, so the destination network and the person answering see the number you present.

Can each campaign or client have its own account?

Yes. Sub-accounts each carry their own balance, limits, call records and number lists, so a campaign or an end client can be reported and controlled on its own.

Which platforms can connect?

Anything that speaks standard SIP: Asterisk and FreeSWITCH based platforms, Genesys and Cisco contact-centre suites over a SIP trunk, cloud contact-centre platforms with SIP connect, and Microsoft Teams voice through a certified SBC. IP authentication is the default, registration is available.

How do you treat outbound campaign traffic?

It is welcome on routes built for it. We ask for the destination mix and expected volumes up front so that capacity and routes are right from day one, and the acceptable-use policy sets out what stays within the rules.
