Analog Line Interconnect via the IP Network

Figure 8-1 shows AudioCodes’ MP-104/FXO mediating between the PBX/PSTN world and the IP

network.

A is an enterprise user in Europe with its own PBX and AudioCodes’ MP-104/FXO

connected to analog lines.

B is a SOHO (Small Office, Home Office) user in the USA, without a

PBX, but with AudioCodes’ MP-104/FXS connected to the phones.

A calling B scenario (Automatic dialing set in the ini file)

1. User A offhooks the phone, hears the enterprise PBX’s dial tone, and dials user B’s phone

number 4133; the call is routed to the analog line connected to the MP-104/FXO which routes

it to the MP-104/FXS that maps it to the phone of user

B calling A scenario (One-stage dialing set in the ini file)

1. User B offhooks the phone, hears the MP-104/FXS device’s dial tone, and dials 4247.

2. The MP-104/FXS device routes the call to the MP-104/FXO which dials it to the enterprise’s

PBX, which routes it to user A’s extension.
