The FXO port only can handle a single call at a time.  Hence, when you have an active call through 0/0/0, any subsequent attempts for calls in and out of that port will not work while the first call is still actively using that port.

If you want to sustain more than a single PSTN call at a time, you need to get another FXO circuit to terminate on this device, and add more dial-peers with equal preference to point out the new circuit.

Hi Steven,

Thanks for your reply, i am using 4 port FXO. Only 2 lines are connected

voice port 0/0/0 444444

voice port 0/0/1 456789

as i understand from your reply that i can only use one line at a time ?

if i have 4 land lines

444444

456789

567891

678912

This means that i need to buy four FXO modules and not use them on the same slot ?

If yes could kindly answer me why they put 4 port at each FXO module.

Thanks

Each FXO port supports a single circuit, for a single call.  Wiring to each FXO port should be 2-wire, straight-through.  So a four port FXO card supports four active calls, via for separate circuits.

You only have dial-peers configured to go out a single port:

dial-peer voice 9 pots

corlist outgoing call-local

destination-pattern 94......

port 0/0/0

prefix 1

!

dial-peer voice 900 pots

corlist outgoing call-int

destination-pattern 90T

port 0/0/0

prefix 0

!

dial-peer voice 937 pots

corlist outgoing call-mobile

destination-pattern 9[3-7]......

port 0/0/0

You need something like this:

dial-peer voice 9 pots

corlist outgoing call-local

destination-pattern 94......

port 0/0/0

prefix 1

!

dial-peer voice 900 pots

corlist outgoing call-int

destination-pattern 90T

port 0/0/0

prefix 0

!

dial-peer voice 937 pots

corlist outgoing call-mobile

destination-pattern 9[3-7]......

port 0/0/0

dial-peer voice 19 pots

corlist outgoing call-local

destination-pattern 94......

port 0/0/1

prefix 1

!

dial-peer voice 1900 pots

corlist outgoing call-int

destination-pattern 90T

port 0/0/1

prefix 0

!

dial-peer voice 1937 pots

corlist outgoing call-mobile

destination-pattern 9[3-7]......

port 0/0/1

wow thanks for your rapid reply,

what i have is 2 land lines RJ11 connected to two different ports of CCME.

So i can use each one of them to make seperate calls, i have configured dial peers also for 0/0/1, but when i use any line the other one will give busy signal. what else should i do , also i am thinking to make the other line use button 7 of the phone to take the other line.

thanks

Your configuration isn't correct if you have dial-peers for both ports

and you can't have two concurrent outbound calls. You don't need to

have different access codes for the different ports. That's excessive;

the IOS call control API can handle this just fine.

Get the following:

sh voice call sum

sh run

sh dialplan number #

And collect the following debugs for the first and second outbound calls:

debug voip ccapi inout

debug vpm sig
