Keep my @company.ch domain : Can I use VTX Teams service with my own Teams domain @company.ch ?

• Problematic: You do own a Microsoft Teams domain like company.ch and you would like to integrate the accounts you have within a "VTX Teams Connect" or "VTX Teams Virtual"
• Information:
  • When subscribing to a VTX Teams service, VTX will provide you with a teams domain like xxxx.teams.ipvoip.ch . This domain will be used to bridge your own Teams accounts ending with "@company.ch" with the VTX service. You will never need to force this domain for your end user
  • During the VTX Teams service setup, you will be asked to create one temporarily user with the @xxxx.teams.ipvoip.ch domain, but only one, and you can delete it as soon as service is running
  • The scrips provided by VTX will allow you to assign numbers to your @company.ch Teams users
• Conclusion: Yes, you can use your own Teams domain @company.ch with VTX Teams service, no need to change your users domain

Multi-Provider : Can I use VTX Teams service in parallel of other provider services ?

• Problematic: You do already have another provider that handles the telephony Direct trunking and you wish to also integrate a VTX Teams service
• Information: VTX does provide a unique teams domain per service and also create unique Call Routing rules including this unique ID
