Teams Voice overview

Teams Voice overview

This article will give you an overview of the different options to use Teams as a phone.

We will talk about advantages and drawbacks, but they are actually the features to consider depending on the licenses already present and/or the desired use.

 


Call2Teams PBX User:  

  • 5 €/Teams user excl. SIP account & Fonzer user & phone number
  • Logic completely in own PBX (Fonzer platform)

Advantages: 

  • Easy to manage once set up, no knowledge of Teams environment needed
  • Management/limitation of the number of simultaneous calls is on the platform (with Fonzer unlimited)
  • Teams available on all devices for 1 subscription (laptop, mobile,...)
  • Hybrid solution possible: standard SIP devices/doorbells and Teams clients combined

Drawbacks: 

  • Many users can get expensive, take phone license into account (only included in O365 E5, otherwise +/- 6,7€ excl. per channel)
  • No real integration with the Teams environment - voicemail, call forwarding, presence-aware queues, ...(but all features of the Fonzer panel)
  • Administration is more intensive: create users in Teams, in Call2Teams and in own PBX

 

Call2Teams PBX Trunk:  

  • €3,6/straight reachable Teams feature (each user, auto-attendant or queue) (= read: for each external number)
  • Trunk required, at Fonzer = €10 + per concurrent call €2.5
  • Take into account:
    • # channels or users per auto-attendant (calling plans that are directly accessible, selection menu, queue)
    • # concurrent calls: 1/3 of the total number of users

Advantages: 

  • Full integration with Teams - manage voicemail, call forwarding, presence from within the Teams client
  • Easy to scale (up or down) - more lines, less lines, add extra users can be changed per month - billing calculates the usage automatically
  • Administration largely in Teams - in the Fonzer platform you put the numbers on the trunk and in C2T you indicate on which feature it should arrive - in other words only 1 place where users are created

Drawbacks: 

  • Becomes expensive when using many direct numbers/services, even if few calls are made
  • If the number of simultaneous lines is badly calculated, congestion and therefore unreachability can occur (can be taken care of in Fonzer failover plan)
  • In-depth knowledge Teams Voice required (editor less visual) to perform the initial setup but no PowerShell knowledge needed

 


Fonzer SBC:  

  • €12/simultaneous call - minimum purchase of 3 channels (€36)
  • Not on Fonzer platform - higher activation cost (€450) but includes full setup of the SBC and pairing of desired numbers excl. portering costs and configuration of Teams.
  • Minimum contract duration 12 months 
     

Advantages 

  • Full integration with Teams - manage voicemail, call forwarding, presence from within the Teams client
  • No other subscription fees, only call charges, regardless of the number of users
  • Administration centrally in Teams, any additional numbers will be put on the SBC by us - administrator only needs the login for O365 environment

Drawbacks: 

  • In-depth knowledge of Teams Voice required for initial setup but also for subsequent maintenance (adding users), PowerShell knowledge is still required for assigning numbers and activating Enterprise Voice.
  • If the number of simultaneous lines is badly calculated, congestion and therefore unreachability can occur (can NOT be handled in failover plan) - so good planning is important!
  • Upscaling is still possible (more simultaneous calls); attention: this is not immediate, it can take several days - downscaling is not possible.
