Using Call Services - ZyXEL Communications MSC1024G Series User Manual

Chapter 18 VoIP
Dual-Tone Multi-Frequency (DTMF) signaling uses pairs of frequencies (one lower frequency
and one higher frequency) to set up calls. It is also known as Touch Tone®. Each of the keys
on a DTMF telephone corresponds to a different pair of frequencies.
Pulse dialing sends a series of clicks to the local phone office in order to dial numbers.
18.1.7.1 VoIP VLAN
Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple
logical networks. Only stations within the same VLAN can communicate with each other.
The system can add IEEE 802.1Q VLAN ID tags to voice frames that it sends to the network.
This allows the system to communicate with a SIP server that is a member of the same VLAN
group. Some ISPs use the VLAN tag to identify voice traffic and give it priority over other
traffic.

18.2 Using Call Services

The VOP supports a variety of call services such as call hold, call waiting, do not disturb, and
so on. These services can be accessed by a user from a telephone connected to the VOP (if the
service is activated in the VoIP > Call Service Profile screen - see
366). The following table shows the default key patterns used to access the supported services.
