Description

The Cisco ISR 3945 is a Cisco 3900 Series Integrated Services Router supplied as a voice bundle, built for branch offices that need local call control and a secure voice gateway at the edge of the network.

This SKU is defined by its voice feature set: Cisco Unified Communications Manager Express (CME) and SRST for 25 endpoints, Cisco Unified Border Element (CUBE) with 25 sessions, and a PVDM3-64 packet voice DSP module for voice processing. CME provides call control at the branch, SRST keeps phones working if the WAN link to the central call manager is lost, and CUBE provides SIP trunk and session border demarcation.

The CME/SRST and CUBE capacities are tied to 25-user and 25-session licensing, so confirm that this matches the size of your site before ordering. Voice processing uses PVDM3-series DSP modules.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Does this router need additional licences for CME/SRST and CUBE?
A: This bundle is configured for 25-user CME/SRST and 25-session CUBE capacity. Permanent feature licences need to be activated on the router for these services to run beyond any evaluation period.

Q: How many phones and call sessions does this bundle support?
A: It is sized for 25 endpoints under CME/SRST and 25 sessions under CUBE. Larger deployments need higher-capacity licences.

Q: What DSP module does it use for voice processing?
A: It uses a PVDM3-64 packet voice DSP module. Other PVDM3-series modules are the compatible family for this platform.

Q: What is the difference between CME and SRST on this router?
A: CME lets the router act as the call controller for a small site, while SRST provides fallback call handling for phones registered to a central call manager when the WAN link is down.
