MeloTel services are functional and stable.
W ehave confirmed that since our recent update to version 5 of our VoIP Panel is incompatible with some firmware versions of Polycom and Cisco Devies using TLS and SRTP encryption. This is specifically a firmware incompatibility and means that if the device is not using the correct firmware version on their device, they will not get a secure connection therefore they will not be able to make or receive calls on that device. Until they are updated.
We are currently rolling out a solution that resolves the issue for more than 98% of the extensions connected to our network.
We have a solution which restores service to devices using our ZTP provisioning. Some devices which are not using our ZTP will be required to either join ZTP provisioning, or update their device firmware to the correct firmware version and then reprogram their device.
Currently the only devices which support TLS/SRTP encryption are as follows;
- Polycom VVX Series: 5.6.0
- Polycom IP Series: 4.0.13
- Cisco SPA504g: 7.6.2a
If you require TLS and SRTP encryption, your must update your firmware to the support version.
If you require assistance, please email firstname.lastname@example.org
We will provide more updates soon.
