I dial by mobile phone from PSTN to my company number and press the extension number for local phone. The IP Phone rings. Now I hang off the mobile phone but the IP Phone still ringing. So what is the problem? Is it caused by FXO setting? Thank you very much.
Thank you for updating everyone on this post. I'm glad to hear that its working fine now. Incase anyone is wondering what the "timeouts wait-release" command does, it is used to configure the delay timeout before the system starts the process for releasing voice ports. From the command lookup tool, the usage guideline states: Use this command to limit the time a voice port can be held in a call failure state. After the timeout, the release sequence is enabled.
