High availability Avaya IPO Server

[avc986780934602]

Dear Sir,

Dear Avaya Support Team,

We are implementing an Avaya IP Office Server Edition High Availability (HA) solution and would appreciate your guidance on the recommended architecture and best practices. Current Environment

• Primary IPO Server: xxx.xxx.xxx.xxx
• Secondary IPO Server: xxx.xxx.xxx.xxx
• ASBCE (SIP Trunk)
• ASBCE (Microsoft Teams)
• IP500v2 Expansion System at the Riyadh branch
• SIP Trunk connected to SBC
• Microsoft Teams integration enabled
• Voicemail Pro
• Call Recording / Media Manager

We would like clarification on the following:

1. High Availability Architecture
   • What is the recommended HA design for two IPO servers with Server Edition?
   • How should the Primary and Secondary servers be configured?
2. Network Connectivity
   • Is it recommended to connect both IPO servers to the same access switch, or should each server be connected to different access switches or directly to the core switches?
   • Is a dedicated network required for SCN communication, or can the SCN link operate over the production LAN?
3. SCN (Small Community Network)
   • What are the best practices for configuring the SCN link?
   • How can we verify that the SCN link is healthy and synchronization is working correctly?
4. Failover Operation
   • If the Primary IPO server fails:
     • Will all IP phones automatically register to the Secondary server?
     • Will internal calls continue to work?
     • Will external SIP trunk calls continue without manual intervention?
     • Will Microsoft Teams calls continue to function?
     • Will Voicemail Pro and Call Recording continue to operate?
5. Licensing
   • Should the Primary and Secondary IPO servers each have their own permanent licenses?
   • Is a separate HA license required for each server?
   • How should the IP500v2 Expansion System be licensed?
6. Voicemail and Call Recording
   • What is the recommended configuration for Voicemail Pro and Media Manager in an HA environment?
   • Are these services automatically synchronized between the Primary and Secondary servers?
7. Synchronization
   • Which data is synchronized between the servers (users, groups, voicemail, configuration, etc.)?
   • How can synchronization status be monitored and verified?
8. Best Practices
   • Are there any Avaya best practice documents or deployment guides available for this architecture?

Thank you for your support and recommendations.
