Cisco IOS Voice, Video, and Fax Configuration Guide
You can connect voice multicasting telephones to routers in the following ways:
• Connect a four-wire E&M telephone, which has no dial and is always off-hook, directly to an E&M
voice interface card that is installed in a voice network module. Configure the E&M interface for
four-wire trunk operation. For information about configuring E&M interfaces, see the chapter
“Configuring Voice Ports” in this configuration guide.
• Connect a conventional telephone to a PBX that is connected to an E&M voice interface card.
• Connect a conventional telephone to an FXS voice interface card that is installed in a voice network
module.
• Connect a conventional telephone to a PBX that is connected through a E1/T1 line to a multiflex
trunk interface card that is installed in a high-density voice network module.
Note The voice multicasting feature supports only one E1/T1 line per high-density voice network module.
