hi everybody, in this moment i try to configure a cisco IP Phone 7931 with multiple line appearance in a CCM 6.1.2, for example: button1 ptn1:dn 6512; button2 ptn2:dn 6512; button3 ptn3:dn 6512 and more, because i found that in this phone does not capture all calls and you can not select which one answer, due to the second call grind the first call, or other solution for this trouble, please any commentary, thank you in advance.

Hi Cristian,


With the 7931, the method that you are using is an excellent way to overcome the "built-in" Max calls per line button restriction;


This is actually a restriction on the 7931 :(


Conrad is a product manager in Cisco IP Communications. He is responsible for many aspects of the phone user interface for the Cisco Unified IP Phone 7970G, 7971G, and 7931G models.



The 7931G was developed for the key system market, common in the retail and commercial space. It was developed in conjunction with the CUCME product team, and many of the features were implemented with a key system in mind.


A single call per line/button is the intended operation, with transfer and conference taking place across lines/buttons.


We wanted to have a large number of line keys, in a small form factor, for retail environments. In this environments, people tend not be so interested in voicemail, directory, and settings, or a large display screen. There is more interest in having a simple User Interface, with a line key light up when the call comes in, and very clear options to hold, transfer, or redial a call.


The phone required some changes to CUCM, and CUCM 6.0 is the first version to support the 7931G. The recommended configuration is to set any DN to have a max-calls of two, and busy-trigger 1, to operate in a key system style of operation.


From this Ask the Expert Event;

This document shows how to use Partitions and Calling Search Spaces to configure multiple lines on one phone with the same DN. It is assumed that the user wants all incoming calls to start on line 1 and forward to subsequent lines if line 1 is busy.

Hi Rob,

Thank you for your response, but i have a little problem. I configure all that indicate in this manual and it works well, i answers several calls and put in hold a call and answer other call, but the trouble in this case is when i want to transfer to other number in the company the softkey appear inactive and i can not transfer any call :(

I can call this IP Phone 7931 without problems and it can call other phone in the company too, the only problem is in the moment that i want to transfer, what can i do?, thank in advance.
