Keep my @company.ch domain : Can I use VTX Teams service with my own Teams domain @company.ch ?[edit | edit source]

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 ?[edit | edit source]

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
Conclusion: Yes, it is possible to setup a VTX Teams service in parallel of an existing service from another provider. You will select which number is handled by which provider.

Frequent Errors[edit | edit source]

New-CsOnlineVoiceRoutingPolicy - Cannot find specified Online PSTN usage[edit | edit source]

Problem: When we run the script to create the call routing, you might get a red error that New-CsOnlineVoiceRoutingPolicy is not working
Symptoms: When running the script to create the call routing, you might get an error "Cannot find specified Online PSTN usage"
Possible Explanation:
- You forgot to create the temporary User "enableteams"
- MS Teams platform is getting some delay and between the time we create the Online PSTN usage and the time we use it in Online Voice Routing Policy, we need to wait for Teams platform to get up to date
Solution:

Verify that you did create the "enableteam" user, cf FAQ:Teams#Create_a_temporarily_user_in_the_.3Cservicenumber.3E.teams.ipvoip.ch_domain
Wait up to 4h and try again to use the script again
