MultiLine PBX Integration Product Document

MultiLine integrates with Cisco Unified Communications Manager (CUCM) to mobilize fixed-line business numbers. The integration allows MultiLine to use existing office numbers for secure mobile calling and messaging. End users have a single number with full compliance features that’s available on both the desk phone and mobile device.

MultiLine’s CUCM integration closes compliance gaps for remote workers, enhances client engagement, and extends the value of your PBX investment. MultiLine integrates with both on-premises and cloud-based CUCM deployments.
