Multiple Calls Per Line
Cisco Unified SRST 9.0 provides support for the Multiple Calls Per Line (MCPL) feature on Cisco
Unified 6921, 6941, 6945, and 6961 SIP IP phones and Cisco Unified 8941 and 8945 SCCP and SIP IP
phones.
Before Cisco Unified SRST 9.0, the maximum number of calls supported for every directory number
(DN) on Cisco Unified 8941 and 8945 SCCP IP phones was restricted to two.
With Cisco Unified SRST 9.0, the MCPL feature overcomes the limitation on the maximum number of
calls per line.
In Cisco Unified SRST 9.0, the MCPL feature is not supported on Cisco Unified 6921, 6941, 6945, and
6961 SCCP IP phones. The maximum number of calls allowed on these phones is two and the maximum
number of calls allowed on octo-line directory numbers on these phones before activating Call Forward
Busy or a busy tone is one.
Cisco Unified 8941 and 8945 SCCP IP Phones
Before Cisco Unified SRST 9.0, the values for the max-dn and timeouts busy commands were
hardcoded for Cisco Unified 8941 and 8945 SCCP IP phones.
In Cisco Unified SRST 9.0, you can configure the max-dn and timeouts busy commands in
call-manager-fallback configuration mode. Use the max-dn command to set the maximum number of
DNs that can be supported by the router and enable dual-line mode, octo-line mode, or both modes. Use
the timeouts busy command to set the timeout value for call transfers to busy destinations.
For configuration information, see the
page 100.
Cisco Unified 6921, 6941, 6945, 6961, 8941, and 8945 SIP IP Phones
In Cisco Unified SRST 9.0, the maximum number of calls for Cisco Unified 6921, 6941, 6945, 6961,
8941, and 8945 SIP IP phones is controlled by the phones.
