We are actively responding to PHP2SHELL, a security vulnerability affecting widely used web software. Our Engineering and Security teams are closely monitoring our systems and taking appropriate measures to address and mitigate any potential risk. At this time, we do not expect inbound or outbound calling traffic to be affected, and normal call processing should continue without interruption. The security and integrity of our systems and customer information remain our highest priority. If we identify a threat requiring additional protective measures, certain systems or services may be temporarily restricted or taken offline, potentially with limited advance notice. We understand how important reliable voice communications are to your business. Our teams will continue to closely monitor the situation and will provide additional updates if there are any changes that could impact SIP.US services.
