16x FXO Ports Configuration on CME

Hi Community,

We have CME router having 16x FXO ports to be connected to PSTN to enable external calling.

How to configure all the ports to enable them all like for example if voice-port 0/0/0 is currently busy, available voice-ports will take over once another incoming or outgoing call take place. Or the available channels/FXO ports automatically take over? 

I have this config script to enable incoming and outgoing PSTN call  on voice-port 0/0/0 then any incoming calls will ring my IP phone with extension 100. Do i need to apply these configuration to all the voice-ports?

enable
configure terminal
voice-port 0/0/0
connection plar 100
caller-id enable
exit

dial-peer voice 1 pots
destination-pattern 9[2-9]......
port 0/0/0
end

dial-peer voice 2 pots
destination-pattern 91..........
port 0/0/0

Thank you in advance.

For outgoing call, configure trunk group which includes all FXO ports. Then in your pots dialpeers point to the trunk group.

For incoming calls, it depends on your telco if they enable hunt across FXO ports

[Nadeem Ahmed · Accepted solution]

Trunk group FXO-16PORTS
hunt-scheme sequential both down

voice-port 0/0/0
Trunk-group FXO-16PORTS
connection plar 100
caller-id enable

voice-port 0/0/1
Trunk-group FXO-16PORTS
connection plar 100
caller-id

and so on .....create same config for rest other ports and associate with trun-group name FXO-16PORTS (you can also define the preference )



dial-peer voice 1 pots
destination-pattern 9[2-9]......
trunkgroup FXO-16ports
end

dial-peer voice 2 pots
destination-pattern 91..........
trunkgroup FXO-16ports

for incoming you can need with telco as already mentioned Mohammed how they are sending call .
