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.

Procedure

The following procedure assumes that you:

To run prt2prt:

  1. Start OAM. For more information about OAM, refer to the NMS OAM Service Developer's Reference Manual.

  2. Start prt2prt by entering the following command:

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 loop start hybrid in slot 0 for the outgoing call. It also uses the wink start protocol on the incoming call and the loop start protocol on the outgoing call.

prt2prt starts and the following information displays:

prt2prt waits for an incoming call.

  1. Put the telephone on stream/timeslot local:0:4 off-hook.

    You hear a relay click.

  2. Dial a three-digit telephone number.

    prt2prt
    plays a message prompting you to dial an extension.

prt2prt connects the two voice streams so that a conversation can take place between the two telephones.

  1. Confirm that the two voice streams are connected by knocking on one mouthpiece. You will hear the knocking on the other mouthpiece.

  2. Hang up the incoming side. prt2prt tears down the call and goes back into a waiting for call state.
