Dear Customers and Partners,

Please be advised that senior MaxoTel voice engineers will be conducting an upgrade to our retail SIP trunking platform (sip.maxo.com.au):

• Date & Time: Saturday, 16th November 2024 from 9:00 PM AEST
• Duration: Approximately 1 hour
• Change: During the window, sip.maxo.com.au (retail SIP trunking, including residential and Voice Line customers) will be migrated to an upgraded call distribution platform.
• Expected Impact: While no direct impacts are expected and we have thoroughly tested with the most common systems connected to our platform, it is possible that some rarely used devices will face compatibility issues. MaxoTel’s engineers will be monitoring our email support channels immediately following the change and throughout Sunday to address any unlikely issues.

Reason for the Change: This upgrade will enhance the service performance and reliability, provides additional resiliency to our voice platform and enables us to deliver new features and technologies.

Firewall Changes: Following this maintenance, the IP addresses that handle call media (RTP) will change. If you run a strict firewall you will need to ensure that it is configured to allow our traffic per https://www.maxo.com.au/support/frequently-asked-questions/configuring-your-firewall-or-acl-whitelist

Important Note for Mission-Critical Applications: If you utilise our SIP trunking platform for mission-critical applications, we recommend contacting our support team in advance to discuss potential alternatives should they be required.

Device Reconnection Tip: If your device or PBX does not automatically reconnect after the maintenance window, please restart your device to restore connectivity. FreePBX and Asterisk users may need to restart their PBX to ensure their PBX accepts calls as normal.

Future Changes: Following the success of the migration of our retail platform, a further maintenance period will be scheduled for our whitelabel SIP trunking platform.

We appreciate your cooperation as we work to enhance our services. Please do not hesitate to contact our support team should you have any queries.

Kind regards,
MaxoTel
