You can configure whether or not an incoming call interrupts an outgoing call that 
is dialing. The incoming call interrupts dialing parameter controls this feature.

When you enable this parameter (1 = enable), an incoming call interrupts the 
outgoing call during dialing and allows the phone to ring for the user to answer the 
incoming call.

When you disable the “incoming call interrupts dialing” parameter
(0 = disable), which is the default, the phone does not interrupt the outgoing call 
during dialing and instead rings the incoming call on another free line (or sends 
busy signal if all remaining lines are busy). You have a choice to ignore the 
incoming call, or answer the incoming call on another line, via the Ignore and 
Answer softkeys that display. If you choose to answer the incoming call, you can 
answer the call, finish the call, and then hang up. You can still go back to the 
original outgoing call and finish dialing out.

Use the following procedures to configure how the IP phone handles incoming 
calls that interrupt outgoing dialing.

1.

On a 53i, you must use the down arrow key to ignore the call. To 

answer the call you must press the line key where the call is coming in.
2.

For all models, if you disable this parameter (0=disable), and the 

phone receives an incoming call while you are dialing an outgoing call, 
you can pick up the call and perform transfer or conference as required.

For specific parameters you can set in the configuration files for enabling/disabling how the IP phones 
handle incoming calls that interrupt outgoing dialing, see Appendix A, the section, 

 on
