We’ve been seeing similar reports across various platforms today. It’s a good reminder of how sensitive these mobile handshakes can be, especially when third-party push servers are involved. At Sip24.cc, we usually suggest keeping an eye on the transport protocols (TCP vs TLS) during these outages, as it can sometimes help the client maintain a more stable “keep-alive” state while the primary push service recovered.
Fingers crossed the Sangoma fix holds up for the rest of your users!
