# MS Teams - Support Scope

## Microsoft CSP Support

CallTower supports any license subscriptions that are purchased through our Cloud Solution Provider (CSP) program for the full term of the Commitment (Subscription). There are generally three types of Microsoft customers: Full CSP, Voice Only CSP, and Non-CSP. Though the support lines may sometimes blur between those customer types and the need for addressing customers and escalations properly, we can generally say what is supported for each customer type.

For CallTower to be considered the "CSP", at a minimum, all Teams Phone Standard licensing would need to be with CallTower (Voice Only CSP).

## Types of CSP Relationships

### Full CSP:

Customers who have all their Microsoft licensing through CallTower. For a detailed breakdown of the scope of support for **Full CSP** customers, see the article: [**Scope of Support - Full Cloud Service Partner (CSP)**](/v1/docs/scope-of-support-full-cloud-service-partner-csp)

### Voice Only CSP:

Voice Only CSP customers are customers who only receive the following voice-related Microsoft licensing subscriptions through CallTower.

- Microsoft Teams Phone Standard
- Microsoft Teams Resource Account
- Microsoft Teams Shared Device
- Microsoft Teams Premium
- Microsoft Teams Essentials with Phone

Our support is limited to features and functionality that are directly associated with these licenses. For a detailed breakdown of the scope of support for **Voice Only CSP** customers, see the article: [**Scope of Support - Voice Cloud Service Partner (CSP)**](/v1/docs/scope-of-support-voice-cloud-service-partner-csp)

### Non-CSP:

Non-CSP customers are customers who have their Microsoft licensing with another CSP or directly through Microsoft.

For a detailed breakdown of the scope of support for **Non-CSP** customers, see the article: [**Scope of Support - Non-Cloud Service Partner (CSP)**](/v1/docs/scope-of-support-non-cloud-service-partner-csp)
