We are implementing VoIP at our office. &nbsp;To do this, we have created &nbsp;a second subnet for the voice traffic (there is also a different subnet for the data). &nbsp;We have created two vlans in our switch (Dell Power Connect 3448P), and we are tagging the voice traffic so the phones will distuingish between the two subnets. &nbsp;My question is: &nbsp;We have a netscreen 5GT. &nbsp;We are trying to enable communication between the two vlans, for some reason we can not get this to work. &nbsp; The trust interface is for the data network and we created a sub interface for the voice network.

Vlan communication

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).
