Dynamics 365 Contact Center - Enable SIP X header support for context transfer

We are announcing the ability to enable SIP X header support for context transfer in Dynamics 365 Contact Center. This feature will reach general availability on November 30, 2025.

How does this affect me?
This feature enhances contextual data exchange between voice agents and external systems in Dynamics 365 Contact Center environments using Direct Routing telephony.

The feature offers two key capabilities:

• Receiving SIP X-Headers: Voice agents can access incoming SIP X header values by defining variables that match the header names.
• Sending SIP X-Headers: During external phone number transfers, voice agents can select up to five variables to pass as SIP X headers.

What action do I need to take?
This message is for awareness, and no action is required.
