# SIP Trunk Status

Once a SIP trunk is configured and operational, the following metrics are displayed for it:

- Trunk Status:
  - - All trunks connected to both the ICPs and SIP service providers are “up”.
  - - A trunking connection cannot be established between the ICPs and the SIP service providers.
  - - The SIP service provider rejected the SIP REGISTER from an ICP. Review the username and credentials configured on your ICP with your account information.
- Reason - If a trunking connection cannot be established, a reason for the failure is provided.
- Calls in progress / Max - The number of calls currently in progress on the trunk, and the maximum number of calls that have been in progress on the trunk during the current session.
- Calls per hour / Max - The number of calls processed per hour on the trunk, and the maximum number of calls that have been processed per hour on the trunk during the current session.
