Both H323 and SCCP can use the Voice VLAN and discover it via CDP:

http://cisco.com/en/US/docs/voice_ip_comm/cata/186_188/3_0/english/administration/guide/sccp/sccpach3.html#wp1122885
However - you can disable it from learning the Voice VLAN through CDP
and instead manually enter the desired VLAN for it to use:
