Description

prt2prt performs call transfer of an incoming call to an outgoing line. It uses the Switching service to connect the voice streams of two calls so that a conversation can be carried out.

Because prt2prt is an actual demonstration of the Switching service, it uses MVIP-95 stream values.

prt2prt only works with an AG-8 board, or an AG-T1/AG-E1 board, or the first span of an AG Quad T1/E1 board.

Procedure

The following procedure assumes that you:

To run prt2prt:

1. Start agmon.

2. Start prt2prt by entering the following prompt:

prt2prt -b 0 -s 4,0 -i wnk0 -o lps0

This command uses board 0 and the DID hybrid in slot 4 for the incoming calls and the loopstart hybrid in slot 0 for the outgoing call. It also uses the winkstart protocol on the incoming call and the loopstart protocol on the outgoing call.

prt2prt starts and the following information is displayed:
