Call Forwarding feature not working for external calls

[Anupam Singh]

there  are 4 IP Phones  connected to CME enabled router 2911.  Router connects to analog pstn  curcuit using FXO port. Call - Forwarding feature is configured on cisco ip phones for internal calls. 4 ip phones have extensions 5000, 5001, 5002 and 5003. If I call 5000 then it forwards call to 5001 if it is busy. But if anyone call from outside network then it plays busy tone. it does not forward call to another ip extension.

I have done PLAR configuration on FXO to make call indide  from outside network.

In Actual How can I configure call forwarding for external calls in CME 7.0.1?  Following option showing  :

RedoqCme#CONF T

Enter configuration commands, one per line.  End with CNTL/Z.

RedoqCme(config)#EPHONE-DN 1

RedoqCme(config-ephone-dn)#FORWARD ?

  local-calls  the calls from local IP phones

RedoqCme(config-ephone-dn)#FORWARD

Hi

I got solution . Normal ADSL line support only one trunk line (only one call in one time) over therefore it not forwarding another call to another extension and making busy tone. We need isdn2 to support 2 calls simultaneously.
