Maintenance ID: 3092
Description: Vitelity engineers will be adding a new rtpengine cluster to the legacy Vitelity network that can signal customers and scale as needed. After this maintenance, RTP may now source from 66.241.96.152 and 66.241.96.153 in addition to their SIP sourcing server, it is advised to ensure network and firewalls allow these sources for RTP.
NOTE: Standard communication to customers with new trunks ALREADY include this list: "...please ensure your firewall is open for the following ranges as Media for these calls may originate from within the following IP ranges:
Impact: If IP ranges listed above have already been whitelisted in Firewalls and Voice servers, no customer impact is expected.
