Callthru

For OMNIVIGIL Solutions IP telephony service customers, our Callthru application uses the cell phone voice plan, so as not to increase data usage and costs whether the customer is on his home network or roaming. This applies to both incoming and outgoing calls. This cellular bridge offers remarkable connection stability, as well as using your offices telephone caller id even when calls are made from your mobile. In addition, you can access the internal extensions directory, which allows you to make an internal call as if you were in the office. Note we suggest combining this paid service with an unlimited calling plan with your mobile service provider, as regular calling charges still apply. If you have a limited plan with your mobile service provider, let us say 2000 minutes, time spent on calls with the Callthru application still count towards that limit.
