Even though iSIP is based in South Africa , SIPTRUNK is still offering the same support, pricing plans and great service to our American based clients.

Operator

Very happy to have a platform with competitive pricing, a self-serve portal, and responsive support when I need it.

Everyone can offer cheap call rates, not all can offer the support like SIPTRUNK.

Competitive pricing, self-serve dashboard, quick and simple self-provisioning.

Became a reseller of SIPTRUNK in April 2020 and never thought of changing to another provider thus far.

Owner 

Commision being paid for being a reseller is always great too.

Network Administrator

There was a complete guide on how to setup our Grandstream UCM PBX with SIP.US and SIP.US also provided a phone number with the service.

They have redundancy options and the quality of the phone calls are just fantastic.

IT Admin

Sometimes when I need help I have to go back and forth with support between SIP and our phone system provider.

Managing director

We only use one trunk for our business and once it is setup, no need to change anything.
