Understanding the cost of Teams Telephony for Office services begins with recognising that you are effectively combining your business telephony and collaboration tools into a single, cloud-based platform. Instead of paying separately for on-premise phone systems, maintenance contracts and multiple communication tools, you consolidate calling, messaging and meetings within one environment. Costs are typically made up of Microsoft 365 licensing, Teams Phone licences, call plans or SIP trunks, and any additional hardware such as handsets or headsets. For small and medium-sized enterprises, this can be structured as predictable monthly per-user charges, making it easier to forecast and control spend. There is usually no need for large upfront capital investment in PBX equipment, and ongoing maintenance is significantly reduced.
Fitting Teams Telephony for Office into your budget depends on the scale of your deployment, the calling patterns of your staff and the level of resilience and support you require. Smaller offices may start with a basic Teams Phone licence and pay-as-you-go or modest call bundles, while larger organisations might benefit from inclusive call packages and direct routing to optimise costs. You can also phase adoption, rolling out Teams telephony to specific departments first and expanding as savings from retired legacy systems are realised. With careful planning, clear analysis of current telecoms expenditure and the right configuration, Teams Telephony for Office can often reduce total cost of ownership while delivering a more flexible, scalable and future-ready communications platform that aligns closely with your operational and financial objectives.
Teams Telephony for Office costs usually start with Microsoft 365 or Office 365 licences, to which you add Teams Phone functionality. This is typically charged per user, per month, allowing you to match licences to actual headcount. You then choose between Microsoft call plans, direct routing via SIP trunks, or a combination of both, depending on your call volumes and destinations.
To fit these services into your budget, begin by reviewing your existing telecoms bills, including line rental, maintenance, call charges and support contracts. Comparing this total with a consolidated Teams solution often reveals savings, especially when legacy ISDN or on-site PBX systems are retired. You can also control costs by standardising on headsets instead of desk phones where appropriate.
Finally, consider implementation and ongoing support. Many organisations opt for a managed service with fixed monthly fees covering configuration, monitoring and local engineering support. This provides predictable expenditure, reduces the need for in-house expertise and helps ensure that your Teams telephony environment remains secure, reliable and aligned with your long-term budget.
