The organisation operates a complex, fragmented voice environment comprising two separate legacy stacks — on-premises Cisco CUCM (with differing soft client versions across the two banking entities), BT trading turret platforms, and disparate voice recording systems (Redbox and Variant). A planned migration to Cisco WebEx cloud was paused due to inadequate change management planning. This role will define and deliver a rationalised voice and UC target state, with particular focus on trading floor voice requirements.
Key responsibilities
* Assess the current voice and UC estate across both banking entities: CUCM, Cisco Cubes, WebEx, trading turrets (BT platforms), voice recording (Redbox, Variant)
* Define a target-state voice architecture aligned to the broader infrastructure transformation
* Develop a structured migration plan to Cisco WebEx (or alternative cloud UC platform), incorporating full change management, user communications, and phased rollout
* Ensure integration requirements are fully assessed prior to any migration: voice recording, turret integration, adjunct services, front office workflows
* Manage end-user impact and change communications — particularly for trading floor users where voice is business-critical
* Evaluate and rationalise voice recording platforms, ensuring regulatory compliance requirements are met
* Work with the network team to ensure QoS, connectivity, and resilience requirements are addressed in the network design
