UK bank Abbey is using technology from Psytechnics to monitor and maintain agreed service levels for its new BT-supplied IP-based telecommunications infrastructure.
BT has implemented a MOS-based (mean opinion score) voice quality service level agreement - which provides a voice quality rating of between one (poor) and five (good) - and is using the Psytechnics technology to monitor the network.
Under the terms of the contract with Abbey, BT has agreed to guarantee a MOS voice quality of at least 3.7, with an aim to consistently deliver a MOS of 3.92.
Psytechnics says its technology enables BT to detect and diagnose faults in a matter of minutes. So far, the voice quality experienced by Abbey users meets or exceeds the requisite 3.7 MOS on 99.9% of calls.
Nigel Chisnal, IT architect at Abbey, says: "With voice quality guarantees in place, the VoIP network allows us to improve both internal and customer-facing communications, and to increase flexibility to meet future business needs."
Abbey is currently rolling out VoIP services across its national network of 800 branches.
