Hello everyone, we're currently expiriencing issue with multiple sip registrations from one device.
Our setup is:
- CUCM 8.6 on VMware ESXi server
- FXS gateway with 24 analog ports.
In order to connect gateway to CUCM we created 24 third-party SIP phones and 24 endusers for digest authorization. But as it turns out only one user can register simultaneously. We've tried to switch from basic SIP device to advanced, that allowed us to have 8 lines be registred at one time but adding additional DNs to this advanced phone and creating additional advanced phone still lead to fail of registration. Analyzing traffic with wireshark we fiund that CUCM send error message "404 Warning: 399 line not configured" in respons to all failed registration requests.
If somebody has any expirience dealing with this issue please share.
If additional info needed i'll be happy to provide it.
