Microsoft Teams + Phone System

Phone System, Calling Plan, E1, E3, E5, International Calling, Audio Conferencing, Direct Routing, SIP, SBC... (oh, my)

If you're considering the E5 License for Microsoft 365 (M365) or Office 365 (O365), or adding Microsoft Phone System to your E3 or E1 users, and then considering either a Microsoft Calling Plan or Direct Routing option, contact Cloud 9 Advisers before you go any further. There is a lot more to consider and if not thought out properly it could cost you. We'll help you navigate the deep, challenging, and often confusing waters when considering Microsoft Teams to replace your current voice communications platform. If you're upgrading from Skype for Business, on one hand it's a no-brainer, on the other there are some intricacies (and credits) to strongly consider first.

Keep in mind the following changes frequently and there are various bundles and packages available. Reach out to Cloud 9 and we'll get you the latest. 

Microsoft Teams license add-ons that you'll need to consider:

    • Phone System license add-on ($8.00/user/month)
    • Plus, Calling Plan ($12.00/user/month for 3,000 minutes/user/month)
      • Or, International ($24.00/user/month) 
    • Or, Direct Routing (no additional MS costs, but costs from the carrier apply, often cheaper)
    • Plus, Audio Conferencing (if and as needed)
    • Toll-free (if and as needed)
    • Teams Rooms (if and as needed)
    • Advanced Communications

One important challenge is redundant and diverse trunking if you're considering using Teams as your new phone system. Microsoft's Calling Plan may be a good fit for your company, however we've found that Direct Routing is most often the better option f(or many, many reasons). Cloud 9 helps clients navigate the myriad providers available that can provide such diversity and redundancy using Direct Routing options for E5 licenses or adding Phone System to E1 / E3 users (rather than just defaulting to Microsoft's Calling Plan option). Besides the limited options with Microsoft's Calling Plan, Microsoft Cloud is not infallible. It can, does, and has failed, often leaving customers completely down, with zero communications capabilties for hours or even days on end. Have you ever heard the old saying, "don't put all your eggs in one basket"?

Another challenge is migration. Microsoft plans likely won't meet the needs of your migration timeline. Their Calling Plan is typically all or nothing and once you sign up, you start paying. If you've got several offices and need to manage agreements and terminations of existing carriers, you won't want double pay for a months on end. The solution is to go with a certified Microsoft Direct Routing provider, but they are not all the same. This is where Cloud 9 can help.

Microsoft will be replacing the ever popular Skype for Business (a.k.a. SFB, or S4B, or SfB) in favor of Microsoft Teams. Teams is already widely available in Microsoft's hugely popular Microsoft 365 and Office 365 suites of cloud-based software (Office 365 is changing too. Soon to be Microsoft 365). If fact, you likely already have Teams today. To be clear Teams is not simply a name change. At its core, Teams is business collaboration and messaging software, but also incorporating voice, video, file sharing and much more. In some respects, there are many similarities to Skype, but Teams is technically an entirely new platform, software, protocols, and for the most part, a new code-base. Regarding the similarities with Skype, Teams does not yet have "full parity" with Skype for Business, but Microsoft is fully committed to Teams as its new UC platform for those organizations considering using Microsoft for such communications purposes. 

Microsoft Teams comes standard with nearly every level of the Microsoft Office 365 packages, for business. It is to be Microsoft's new Unified Communications platform that combines persistent business team chat (with Slack squarely in its crosshairs), video, file sharing, task mgmt., meetings, and application integration. Teams is generally designed for corporate groups, teams, or departments for both internal and external parties as members. Microsoft (Teams) Phone System is included with their enterprise licensing, E5 package, or can be added separately for E1 and E3 users. Once you add Phone System to any specific user, you'll need to decide on Microsoft's Calling Plan or Direct Routing options for external calling capabilities. Calling Plan is a limited set of packaged minutes and may not be useful or flexible enough for many enterprises. Calling Plan allows users to make/take external, PSTN-Public Switched Telephone Network calls. Other considerations when adding Phone System to an E1/E3 license are International Calling and Audio Conferencing. These two additions are likely needed for a select group of users (e.g. executives, and sales) which will need to be added separately. The Office 365 E5 license makes this decision a little easier because Audio Conferencing is in the package. The decision then simply becomes Calling Plan (plus individual International Calling users) or Direct Routing and Cloud 9's assistance with the right trunking options and carriers. 

Microsoft Phone System + Direct Routing allows for far greater flexibility, and often far lower monthly costs, compared to simply adding Calling Plan directly. Additionally, for enterprises with heavy investments in legacy PBX systems or currently in contract with PSTN carriers, Direct Routing will allow enterprises to slowly roll-out the migration.

For pure-cloud, and greenfield roll-outs, there are very few SIP Trunk providers available today that are truly and directly approved/certified by Microsoft for Direct Routing, although that list is growing everyday. While there are dozens, even hundreds of carriers that provide "Microsoft Teams SIP Trunking", that does not necessarily mean they are certified Direct Routing partners. In other words, their SIP is not native TLS. How they get around that is to simply use their own managed Session Border Controller (SBC) then deliver the trunks to you. This also means you should be even more diligent in your search. Many of the "original" directly certified carriers are international telecommunications providers that don't necessarily "reach" the US. We have also found, for the very few that are US-based, their services are particularly expensive, compared to "traditional" SIP and similar to what one would find with Microsoft Calling Plan pricing options and packages. The good news with Direct Routing is, technically, it doesn't matter. You can use almost any carrier and even any trunking you'd like, which can help keep migration costs down dramatically and avoid any unnecessary overlaps with contracts of current carriers vs. Microsoft Calling Plan. In most cases, the only "trick" is to get the proper, and Microsoft approved, customer-provided SBC-Session Border Controller. With the proper SBC in place clients can use old fashioned POTS lines, traditional PRIs, or nearly any SIP Trunk provider they wish. So, if you're still under contract for some of those legacy telco trunks, you can still use them until the contract runs out. 

As mentioned previously, for the cloud-purists, many carriers and even Hosted VoIP/UCaaS providers offer SIP Trunking and MS Teams integration. While they may not be "certified" for Direct Routing (thereby keeping their costs down by not having to pay the exorbitant "participation" and certification fees to the mothership), many will manage and maintain their own cloud-based, Microsoft approved SBC so you don't have to!  THey then pass on the "Teams-ready" dial-tone on to you.
