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
Requirements
- Cisco Unified Communications Manager (CUCM): design, administration, and migration
- Cisco WebEx (cloud UC): deployment, migration from on‑premises, integration
- Cisco Cube (session border controller) configuration and dial plan design
- Trading turret platforms: BT ITS or equivalent — integration and interoperability
- Voice recording platforms: Redbox, Verint, NICE, or equivalent — regulatory compliance context
- SIP trunking, dial plan design, and PSTN gateway architecture
- QoS for voice and UC across LAN/WAN environments
- Understanding of MiFID II / FCA voice recording obligations in financial services
Advantageous
- CCNP Collaboration or equivalent
- Experience with soft client migration (Java‑based to WebEx or Teams)
- Knowledge of front office / trading floor communication requirements
- Strong project and change management discipline — able to design and execute structured migrations with appropriate user engagement
- Ability to manage stakeholder expectations across trading floor, IT, and compliance audiences
- Methodical and risk‑aware, with particular sensitivity to business‑critical voice systems
