Microsoft Azure Communication Phone Numbers Client Library for Python
Decision gist · record as of 2026-08-14
Yes, if you are building on Azure Communication Services and need programmatic phone number management. The package is production-stable, actively maintained, has low install friction, and carries no known vulnerabilities. Install it only if you have an Azure subscription and a deployed Communication Services resource; without those prerequisites, the package cannot be used.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires an active Azure subscription and a deployed Azure Communication Services resource with endpoint and credentials configured.
- Low install friction with three lightweight runtime dependencies.
- Active maintenance with recent commits and production-stable status; requires Python 3.9 or later.

What it is and what it does
This package is the Python client library for Azure Communication Services' phone number management APIs. It provides two main clients: PhoneNumbersClient for acquiring and managing phone numbers (geographic, toll-free, and mobile types), and SipRoutingClient for configuring direct routing infrastructure. The package handles the full lifecycle of phone numbers—searching available numbers, reserving them temporarily, purchasing for your Azure resource, and releasing them when no longer needed. It also manages SIP trunk configuration and voice routing rules for connecting your existing telephony infrastructure to Azure.
The package depends on azure-core for authentication and HTTP transport, isodate for date/time handling, and typing-extensions for type hints. It requires Python 3.9 or later and integrates with Azure Identity for credential management, supporting both Azure Active Directory and connection-string authentication patterns.
Use it for
- Search and purchase phone numbers in specific countries and regions for your communication application.
- Retrieve details about already-purchased phone numbers assigned to your Azure resource.
- Set up SIP trunks and routing rules to connect your on-premises telephony system to Azure Communication Services.
- Browse available phone numbers by country and type before committing to a purchase via the reservation API.
- Release phone numbers that are no longer needed to free up capacity and reduce costs.
