IMS Voice Calls

SIP, VoLTE, & VoWiFi

With increasing methods of initiating and terminating voice calls on your network, there is a much greater possibility for errors. Packet Switched call methods (SIP, VoLTE and VoWiFi) offer excellent improvements to the customers experience, and are fast becoming the preferred methods of call initiation.

Are you sure that you have tested all possible combinations of start and endpoints, and verified that the metering and billing of the generated records are all aligned? BluGem’s team of experts is on hand to provide a snapshot or long term automated testing across our global network of devices.

Our network of the latest real Android devices and soft SIP clients enable us to fully automate initiating or terminating test events using any of the available calling methods.
