Is it possible to generate billing using the MultiVOIP Gatekeeper solution by itself? Is it possible to generate a log, to know how much time each extension was using the MVP solution?

The MultiVOIPs and Gatekeeper do not include any built-in billing capabilities. Our MultiVOIP Manager SNMP configuration utility, when used in conjunction with the voips, will create a Call Detail Record that can be used for billing purposes. This CDR can be imported into 3rd-party billing software that supports importing a comma-delimited file.
