Troubleshooting SIP Registration
If a SIP account is not registering successfully please check the following:
1. Confirm all account registration information has been entered correctly.
2. Confirm the SIP interface (SIP1 or SIP2) configured as the Via in the account is enabled.
3. Verify that the Via selection in the SIP1 or SIP2 interface settings corresponds with the
network interface being used by the codec to register the account. E.g. ETH1, ETH2.
