Our Telephony Engineers perform maintenance on our SIP proxy servers in the Europe region. This maintenance will not disrupt service or cause TLS connections to be broken/restarted.
The TLS certificate for our SIP proxy server sip.telnyx.eu (185.246.41.140 and 185.246.41.141) will be changed during this maintenance. This is important for some customers who use an SBC (or other appliance) and have our certificate loaded into the SBC. Note that the same certificate chain is being used with the new certificate, so this should affect only those customers who load our server certificate rather than the CA certificate into the SBC.
This information also applies to some customers who use TLS with desk phones (poly phones, for example) and who have our server certificate loaded into the phones.
The new certificate will have this serial number, issuer, and fingerprint. - Serial Number: b5:3d:a3:cd:a4:df:d2:26:5e:1e:25:2b:63:06:5b:73 - Issuer: C=GB, ST=Greater Manchester, L=Salford, O=Sectigo Limited, CN=Sectigo RSA Domain Validation Secure Server CA - SHA1 Fingerprint: 8C194D79C50935D6E0CCE673580DBE65CF3B6ACA
It's available for download from this (non-Telnyx) website. The intermediate certificate is not included here, but can be seen at sip.telnyx.eu:5061 today. Note that the same intermediate certificate will be used with this renewal, so we expect that any customer/client who trusts the existing certificate will trust the new one, too (the exception is the use of SBCs or Polycom phones mentioned earlier). - https://crt.sh/?id=18179342181 - https://crt.sh/?d=18179342181
