# 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.

To view the status of SIP trunks on MBG:

1. On the MBG main page, click the SIP trunking tab and click Status.
