PAP2T Connectivity
As shown in the following figure, the PAP2T has two FXS ports (voice lines 1 and
2).
NOTE
The IVR functions are accessed by connecting an analog telephone to Line 1.
For proper operation, the service provider should use an Outbound Proxy to
forward all voice traffic when the PAP2T is located behind a router. If
necessary, explicit port ranges can be specified for SIP and RTP.
