Sinch Elastic SIP Trunking will be optimizing routing for inbound calls. The scheduled work is not expected to impact services. This is being sent as a courtesy notice in the event that you experience issues with your service during the maintenance window.

Currently, we are sending inbound calls from:
SIP Signaling IPs 206.146.133.0/28
RTP IPs 206.146.133.128/26

Following the scheduled maintenance, you may also see calls from:
SIP Signaling IPs 206.146.137.0/28
RTP IPs 206.146.137.128/26

Please be sure to allow both IP ranges prior to the maintenance.
