| Dear Customer, In response to the Heartbleed Bug, we are reaching out to customers to communicate the status of RingCentral’s service. The OpenSSL Heartbleed Bug is a critical security vulnerability that affected many Internet sites. More information on the bug can be found at www.heartbleed.com. The RingCentral service was not vulnerable to the Heartbleed Bug. Additionally, we have worked with our phone manufacturers. Only Polycom VVX phone models have the vulnerability, and this is being addressed by Polycom. We will push out the update once available. Cisco phones and the remaining Polycom phones are not vulnerable. Note that customer messages are not stored on the desk phones. As always, we recommend that customers configure their local networks using best practices to ensure that the user interfaces on VoIP phones are protected by customer firewalls. Regards, The RingCentral Team |
