Hi batumi,
You can find your answer to the next
"When you enable port security on an interface that is also configured with a voice VLAN, set the maximum allowed secure addresses on the port to two. When the port is connected to a Cisco IP phone, the Cisco IP phone requires one MAC address. The Cisco IP phone address is learned on the voice VLAN, but is not learned on the access VLAN. If you connect a single PC to the Cisco IP phone, no additional MAC addresses are required. If you connect more than one PC to the Cisco IP phone, you must configure enough secure addresses to allow one for each PC and one for the phone."
There are also some guidelines that you should take into consideration when you configure port security to voice vlan.
For instance you can not configure the sticky command to voice vlan

After enable port security on an interface that is also configured with a voice VLAN, the number of MAC addresses that is set on the port is 1.
When you enable port security on this interface, you must set the maximum allowed secure addresses on the port to at least two. Otherwise the selected Violation will occur, because the switch doesn’t set the maximum number of Mac´s on the port automatically to two.
