Anyone know whether using dual-line will limit the max directory that is available to use in SRST?
Solved! Go to Solution.

Hi Vinh,
Just to add a reference to the good info from Kelvin (+5 points for this Kelvin)
In the case of SRST a Virual Port to accomodate Dual Line is = to 1 DN :)
To set the maximum possible number of directories or virtual voice ports that can be supported by a router and to activate dual-line mode, octo-line mode, or both modes, use the max-dn command in call-manager-fallback configuration mode. To return to the default number of directories or virtual voice ports and to deactivate the dual-line mode or octo-line mode, use the no form of this command.
max-dn max-no-of-directories [dual-line | octo-line] [preference preference-order]
[number octo-line]
no max-dn
Syntax Description
Command Default
0 directory numbers, 1 channel per virtual port, 8 channels per virtual port, 0 preference, 8 numbers
max-no-of-directories
Maximum number of directory numbers (dns) or virtual voice ports supported by the router. The maximum possible number is platform-dependent; see the Cisco IOS command-line interface (CLI) help. The default is 0 directory numbers and 1 channel per virtual port.
dual-line
(Optional) Sets all Cisco Unified IP phones connected to a Cisco Unified SRST router to one virtual voice port with two channels.
octo-line
(Optional) Sets all Cisco Unified IP phones connected to a Cisco Unified SRST router to one virtual voice port with eight channels.
The max-dn command limits the number of Cisco Unified IP phone directory numbers or virtual voice ports available on the router.
The dual-line keyword facilitates call waiting, call transfer, and conference functions by allowing two calls to occur on one line simultaneously. In dual-line mode, all Cisco Unified IP phones on the Cisco Unified SRST router support two channels per virtual voice port.
The octo-line keyword facilitates call waiting, call transfer, and conference functions by allowing eight calls to occur on one line simultaneously. In octo-line mode, all Cisco Unified IP phones on the Cisco Unified SRST router support eight channels per virtual voice port.

Per my experience no it does not limit the max directory setting.
