Hi friend, initial steps:


1. Configure your gateway (h323 or mgcp)

2. Configure your route-patterns

3. Assign the partition, CSS, MRGL, Region, Location to your gateway.


1. Initially, for making calls to the PSTN numbers, create a dial-peer pots with a destinatton pattern .T, the port should be your FXO port

dial-peer voice 100 pots

destination-patterns .T

port 1/0 (FXO port)

2. To receive calls from the PSTN to your IPT network, configure a connection plar pointing to an internal ip phone in your FXO voice port.

voice-port 1/0 (FXO port)

connection plar 1212 (DN IP Phone).

We can help you if you post your gateway configuration.

Hope this help
