A dual-line directory number has the following characteristics:
â¢One voice port with two channels.
â¢Supported on IP phones that are running SCCP; not supported on IP phones that are running SIP.
â¢Can make two call connections at the same time using one phone line button. A dual-line directory number has two channels for separate call connections.
â¢Can have one number or two numbers (primary and secondary) associated with it.
â¢Should be used for a directory number that needs to use one line button for features like call waiting, call transfer, or conferencing.
â¢Cannot be used for lines that are dedicated to intercom, paging, message-waiting indicator (MWI), loopback, and music-on-hold (MOH) feed sources.
â¢Can be combined with single-line directory numbers on the same phone.
Note that you must make the choice to configure each directory number in your system as either dual-line or single-line when you initially create configuration entries. If you need to change from single-line to dual-line later, you must delete the configuration for the directory number, then recreate it.
I think you have miss configured the phone button command..that is...to configure a hunt
using shared line you have to follow the following procedure
so you have 4 shared line with same number and you can assign it to four lines like this
button 1:1 2c50,49,48,47 3m2 4m3
button 1:5 2c50,49,48,47 3m2 4m3
button 1:7 2c50,49,48,47
button 1:14 2c50,49,48,47
You should use (2c50,49,48,47) not (2o50,49,48,47) So that in the second line of 4,5,7and 18 phones are in a shared hunt group and if a call comes to 270 the first preference line will ring first and if it is busy the call will go to the next preference line. In your case if one call comes and attempt for a second call to 270 the call will assume busy and go to voice mail or AA if configured on that line
