Hey Guys,
We're going to be announcing this in a few days, and I'm dropping this here early. We're adding additional IPs to our network because we have been adding significantly more interconnectivity to the PSTN over the last year as part of an enormous network upgrade. As part of this upgrade, we simply needed more networking capacity. (This will also help us with DDOS mitigation)
Specifically, you will need to add these IPs:
44.199.94.192/27
3.144.141.64/27
3.101.177.224/27
35.85.225.96/27
3.99.65.224/27
(These IPs will do not currently support outbound calling, but we may add that ability via the dns record below at a later date)
You will also need to update your outbound calling to use these:
First Priority - na.skyetel.com
Second Priority - 15.197.157.235
Third Priority - 3.33.143.204
I've updated the IP Address doc here:
https://support.skyetel.com/hc/en-us/articles/360041173493 (you'll need to be signed in to read this).
Anecdotally, the IPs used for outbound calling now use Anycast; so you'll be automagically connected to the region nearest you when you use those IPs.
These IPs will be required by 12/1/2021 - so the sooner you can do them the better :). We will be updating na.skyetel.com with the new IPs later this week.
Feel free to drop in a comment with feedback or questions.
