## Timeline of updates

- **maintenance scheduled** 2026-09-07 17:22 UTC: Our Telephony Engineers will perform maintenance on our primary inbound SIP proxy server in the Canada (sip.telnyx.ca: http://sip.telnyx.ca) region. This is a follow-on from last week's maintenance, during which our secondary server (64.16.250.13) had its certificate renewed but the work on the primary server (192.76.120.31) was postponed. - https://status.telnyx.com/incidents/rpetfdsy During this maintenance, our TLS certificate for the primary proxy server will be renewed. These important changes will happen. - We'll switch Certificate Authority from Sectigo to LetsEncrypt. - The "clientAuth" EKU is being deprecated, which may affect customers who use mTLS (mutual TLS) for SIP signaling. Note that the same certificate will be used for both servers when this is complete. Note: A notification was sent to customers recently (21st July, subject "Action may be required: TLS certificate changes for Telnyx SIP proxies"); more-detailed information can be found online here. - https://support.telnyx.com/en/articles/15948276-upcoming-tls-certificate-changes-for-telnyx-sip-proxies
