Important Notes
This section contains these topics:
•
Shared Line Support
Shared lines are not supported on Cisco Unified SIP Phone 3951. The Cisco Unified SIP Phone 3951 Administration Guide for Cisco Unified Communications Manager 6.0 and 5.1 and Cisco Unified SIP Phone 3951 Phone Guide for Cisco Unified Communications Manager 6.0 and 5.1 erroneously state that shared lines are supported.
DTMF Support on Cisco Unified SIP Phone 3951
Cisco Unified SIP Phone 3951 requires the use of gateways with media termination point (MTP) transcoders that support RFC 2833, such as the Cisco 3825 Router in order to support dual tone multi-frequency (DTMF). You can configure the system to support DTMF by either configuring the MTP on a transcoding device that supports RFC 2833 or by checking the Require DTMF Reception check box for each registered Cisco Unified SIP Phone 3951 in Cisco Unified Communications Manager Administration, Phone Administration window.
