5.5.4.1 Dialing from Remote Extension
(Phone connected to MP-108/FXS)
$ To configure the call take the next 6 steps:
1. Take the handset off, to hear the dial tone coming from PBX, as if the phone was connected
directly to PBX.
2. MP-108/FXS and MP-108/FXO establish a voice path connection from the phone to the PBX
immediately after the phone handset was raised.
3. Dial the destination number (the DTMF digits are sent, over IP, directly to PBX).
4. All tones heard are generated from PBX (such as ringback, busy or fast busy tones).
5. There is one-to-one mapping between MP-108/FXS ports and PBX lines.
6. The call is disconnected when the phone connected to MP-108/FXS goes on-hook.
5.5.4.2 Dialing from other PBX line, or from PSTN
$ To configure the call take the next 5 steps:
1. Dial the PBX subscriber number the same way as if the user’s phone was connected directly
to PBX.
2. Immediately as PBX rings into MP-108/FXO, the ring signal is “send” to phone connected to
MP-108/FXS.
3. Once the phone’s handset, connected to MP-108/FXS, is raised, the MP-108/FXO seizes the
PBX line and the voice path is established between the phone and the PBX line.
4. There is a one to one mapping between PBX lines and MP-108/FXS ports. Each PBX line is
routed to the same phone (connected to MP-108/FXS).
5. The call is disconnected when phone connected to MP-108/FXS goes on-hook.
5.5.4.3 MP-108/FXS Configuration (using the FXS ini file)
$ To Configure the MP-108/FXS ini file take these 4 steps:
1. Configure in FXS ini file the endpoint numbers from 100 to 107.
2. Configure TargetOfChannel table to include phone numbers of MP-108/FXO Gateway: such
as TargetOfChannel0 = 200. (When phone connected to port #0 goes off-hook, the FXS
Gateway automatically dials “200” number).
3. Configure IP to phone table, to IP address and numbers of the FXO Gateway: such as
Prefix=20,10.1.10.2 (where 10.1.10.2 is an IP address of MP-108/FXO).
4. Set ‘IsDialNeeded = 0’ to activate automatic dialing, when the handset goes off-hook.
