Avaya IP Office R12 Upgrade — Short-Term Contractor (Riyadh, Saudi Arabia)

Role: IP Office Engineer / ASBC Specialist (Contract Basis)

Location: Riyadh, Saudi Arabia (on-site required for cutover; remote possible for some config work)

Duration: Estimated 8–11 engineer-days

Engagement type: Short-term project contract, not full-time employment

Project scope:

Upgrade of an existing Avaya system to IP Office R12 Server Edition. Hardware and licenses are already procured by the client — this role covers installation, configuration, and testing only.

Responsibilities:

Install IP Office Server Edition on 2x Dell R240 servers (primary/secondary resilience setup)

Apply and validate R12 Server Edition + Power User licensing (20 users)

Configure extensions, voicemail, hunt groups, and auto-attendant call routing

Set up and harden ASBC (Session Border Controller) — sessions, encryption, security rules

Reconnect/test SIP trunks and number routing

Integrate with company Active Directory (user/login mapping)

Configure Microsoft Teams direct routing/interop

Set up TeleTiger billing system (300-user license)

Lead testing and cutover (may require after-hours/weekend work to avoid live call disruption)

Provide documentation and basic admin handover/training

Required experience:

Hands-on Avaya IP Office Server Edition deployment experience (R11/R12 preferred)

ASBC configuration and security hardening experience — non-negotiable, this is the highest-risk part of the project

SIP trunking and number porting experience

Active Directory integration experience

Microsoft Teams direct routing/interop experience (a plus, can be split to a separate specialist if needed)

Avaya certification (ACSS/ACIS or equivalent) preferred but not mandatory if experience is demonstrable.
