Agentlogin dial command not working


Here our setup

We used elastix asterisk 1.1.6 and phone is analog connected to linksys pap2t. I tried to use agent login using the dial command 11 in analog phone and it state that the “local is unavailable”. I tried to use xlite using 8 (queue number + ) and agent login success. I tried to use 8 in analog phone connected to linksys pap2t but busy tone i heard. But i don’t see dial command in the configuration in pap2t , how to i fix this problem.
