FXO Trunk Group -- Driving Crazy

I configured trunk group with FXO ports with the config below. After a outgoing call is made through each voice-port, no further calls can be made (get a busy tone). In the "sh trunk group" output, I see that there is no free trunks available. The "sh voice port summ" shows me that the voice-ports are up/dorm/idle which is fine. Only way to again make calls is to remove the trunk-group command from the voice-port and again add it.

Anyone faced this problem before, and can please check if my config needs any additions. I tried with all available "hunt-schemes", still I get the same problem.

Relevant Config:-

---------------

trunk group FXO-PORTS

max-calls voice 1000

hunt-scheme round-robin

voice-port 1/0/0

trunk-group FXO-PORTS 1

signal groundStart

!

voice-port 1/0/1

trunk-group FXO-PORTS 2

signal groundStart

dial-peer voice 9191 pots

trunkgroup FXO-PORTS

destination-pattern 911

prefix 911

Output before making any calls:-

------------------------------

DALLAS#sh trunk group

Trunk group: FXO-PORTS

Description:

trunk group label: FXO-PORTS

Translation profile (Incoming):

Translation profile (Outgoing):

Hunt Scheme is round-robin

Max Calls (Incoming): NOT-SET (Any) 1000 (Voice) NOT-SET (Data)

Max Calls (Outgoing): NOT-SET (Any) 1000 (Voice) NOT-SET (Data)

Retries: 0

Trunk 1/0/0 Preference 1

Total channels available : 1

Data = 0, Voice = 0, Pending = 0, Free = 1

Trunk 1/0/1 Preference 2

Total channels available : 1

Data = 0, Voice = 0, Pending = 0, Free = 1

Total calls for trunk group: Data = 0, Voice = 0, Pend = 0, Free = 2

Current trunk : None Selected

Outputs after making two calls, one through each port:-

----------------------------------------------------

DALLAS#sh trunk group

Trunk group: FXO-PORTS

Description:

trunk group label: FXO-PORTS

Translation profile (Incoming):

Translation profile (Outgoing):

Hunt Scheme is round-robin

Max Calls (Incoming): NOT-SET (Any) 1000 (Voice) NOT-SET (Data)

Max Calls (Outgoing): NOT-SET (Any) 1000 (Voice) NOT-SET (Data)

Retries: 0

Trunk 1/0/0 Preference 1

Total channels available : 1

Data = 0, Voice = 1, Pending = 0, Free = 0

Trunk 1/0/1 Preference 2

Total channels available : 1

Data = 0, Voice = 1, Pending = 0, Free = 0

Total calls for trunk group: Data = 0, Voice = 2, Pend = 0, Free = 0

Current trunk : 1/0/1

As you can see here Free = 0, so I cannot make any new outgoing calls.

Thanks,

Partha
