Voice Gateway- FXO ports configuration

Hello Everyone,

Need some urgent help form Voice Experts please reply.

1. I have two fxo ports configured, one is for IVR and another is direct line on one cisco IP Phone and i used the commad connection plar for it.

    when i call from outside the call is forwarded to specific number (ex 1246) that is configured for direct line but when i disconnect the line from outside         call is infinitely ringing on IP Phone. I am unable to understand what setting it require.

voice-port 0/1/1

cptone SA

timeouts ringing 5

connection plar 1246

caller-id enable

2. As two FXO ports are configured one for direct line and another for IVR. I want to dedicate port 0/1/1 only for direct line for inbound and outbound calls. But when i dial the external call from any of the IP Phone it will pick either voice port 0/1/0 or 0/1/1 based on availability. I want to restrict port 0/1/1 only for direct line on only 1 IP Phone no other phones should use this FXO line.

3. When i call any number from outside IVR or Direct line and disconnect the line and dial again soon after disconnection. Gateway does not release the call for around 2 minutes. Even though there is no Inbound or Outbound call but still it show line busy signal.

Please Advice on the above issues.

I have attached the config file. Voice gateway is 2951 and Call Manager version is 8.6 (only one server as publisher), IP phone model is 7962
