47 Chapter 2 Using the Utility
2.12 Voice Calls
This section covers how to initiate and receive calls over an ISDN through the analog ports on
your ISDN TA and introduces supplementary services including call hold, call waiting, call
transfer and three-way conference.
Note: You can only use the utility, AT command or Tone command to activate or
deactivate call waiting. Use the flash key and the digit keys on the telephone to
invoke supplementary services (see Section 2.12.4 on page 48).
2.12.1 Placing a Voice Call
You can use your analog phone connected to the PHONE 1 and PHONE 2 ports to dial out a
call directly. With the Quick Dial feature, you can place an ISDN voice call by dialing “nn#”
(where nn=00-09, pre-stored phone number index). You must store up to five phone numbers
first by using the utility, AT commands or tone commands. Refer to Section 2.9 on page 40 on
how to store a phone number with the utility.
2.12.2 Answering a Voice Call
To answer an incoming call, just pick the receiver when that telephone is ringing.
Voice calls are routed to one or both of the analog ports (PHONE 1 or/and PHONE 2) based
on the phone number assignment when they are received. When the same number is assigned
to both ports, you can choose the port you want to receive calls by setting the priority of the
ports. If two ports have same priority, both ports receive ring signals. See Section 2.11.4 on
page 45 on how to configure port priority.
When answering an incoming call, the TA will first be identified if the calling number matches
the MSN settings. The Multiple Subscriber Number (MSN) supplementary service enables
multiple ISDN numbers to be assigned to a single ISDN BRI line. It allows the caller to select,
via the public network, one or more distinct terminals from a variety of terminal choices. Since
the TA supports many different communication protocols and two analog adapters, each of
these ports can individually be assigned to a different ISDN number (see Section 2.11.1 on
page 43 for more information).
Port Priority To set the same priority for both two ports, select Port priority to Both ports
are same priority.
To set the PHONE 1 port to have the first priority, select Port priority to
Analog Port 1 is high priority.
To set the PHONE 2 port to have the first priority, select Port priority to
Analog Port 2 is high priority.
Dialing method Configure how to send the signaling message with the phone number. Options
are OVERLAP sending and EN-BLOC sending.
