We would like to inform you that we added an additional source IP from which we send you callback notifications.
At the moment this only affects Voice Clients integrating via the API who may see callbacks coming from the new IP: 184.108.40.206. Clients using SIP trunk or integrating through any of our partners will not be affected.
If you have a restriction on the IPs that can send requests to callback URLs, kindly allow this IP in addition to the ones previously communicated (220.127.116.11, 18.104.22.168 and 22.214.171.124) to avoid missing our notifications.
Thanks and warm regards, Africa's Talking Team.
