Chapter 40 Cisco IP Phones

Directory Numbers

Note This check box only applies to the actual directory number and partition. It does not apply to the other device settings such as voice-messaging profile, call forwarding options, or MLPP. If any of these settings are changed for a shared line, then all devices get changed.

For directory number configuration and update information, see “Configuring Directory Numbers” in the Cisco CallManager Administration Guide. For information about deleting and updating unassigned directory numbers, see “Deleting Unassigned Directory Numbers” and “Updating Unassigned Directory Numbers” in the Cisco CallManager Administration Guide.

Making and Receiving Multiple Calls Per Directory Number

Cisco CallManager supports various behaviors when users make and receive multiple calls per DN: Transfer/Direct Transfer and Conference/Join.

Transfer allows different line appearances in one device to initiate independent transfer transactions and allows multiple transfer transactions per line appearance per device.

Conference allows different line appearances in one device to initiate independent conference transactions and allows multiple conference transactions per line appearance per device.

Note Devices that do not support multicall display, such as Cisco IP Phone Model 7910, cannot transfer or conference two existing calls together.

Transfer and Conference Behavior

If only one active call exists on the directory number, the first invocation of a feature results in putting the active call on hold and initiating a new call by using the same directory number. When the new call gets set up, the second invocation of the same feature starts the feature operation. The first invocation of Transfer/Conference will always initiate a new call by using the same directory number, after putting the active call on hold.

In terms of compatibility, the Cisco 7936 works seamlessly with Cisco Unified Communications Manager and other VoIP platforms, ensuring that organizations can integrate it into their existing communication systems with ease. This interoperability allows businesses to leverage their technology investments while providing a reliable conferencing solution.

Security is another critical aspect of the Cisco 7936. The device supports encrypted voice communication protocols, ensuring that sensitive discussions remain private and secure. This is particularly important in corporate settings where confidentiality is paramount.

In summary, the Cisco Systems 7936 conference phone delivers exceptional audio quality, ease of use, and flexible deployment options.
