The Business Challenge
Virtually every organization needs to route calls to appropriate workgroups or departments. However this usually means involving the IT department to set up and maintain the call groups. On top of that, there is little to no reporting for managers to ensure that service levels are being met without blowing the budget on a formal contact center solution.
Common considerations, challenges and issues include:
- Can Teams Phone System completely replace my on premises PBX?
- Teams does not include Contact Center functionality, what are my options here?
- How do I deal with existing IP phones which have not been fully depreciated?
- Can I use my current telco provider with Teams or are there other options available?
- My company needs to migrate to Teams over time, how do I integrate my PBX users with Teams users?

Customer Use Scenario – A Phased Migration Strategy
After evaluating multiple Cloud-based Unified Communications solutions, The Jane Doe Company selected Microsoft Teams Phone System to replace their current LandTel PBX system. Having dozens of regional offices plus an on premises Contact Center, the company needed to migrate to Teams in phases.
- Altigen’s Professional Services team designed a plan for JDC to first deploy Teams for all employees, enterprise-wide, improving collaboration and getting the employees familiar with the new Teams UI.
- Next, based on JDC’s requirement to migrate one regional office per week to Teams Phone System, Altigen developed integration between Teams Phone System and JDC’s LandTel PBX, JDC’s LandTel PBX, enabling all employees to continue to call one another via extension dialing.

Once the migration was completed for all regional offices the corporate HQ users then were migrated to Teams Phone System – which included replacing the expensive LandTel Contact Center with Altigen’s Cloud Contact Center solution. JDC now enjoys all of the benefits of Teams, with a complete Cloud communications solution, all fully supported by Altigen.
