What are Jive's IP blocks?
Jive Voice handsets must have unfiltered access to Jive’s network ranges. These IPv4 and IPv6 ranges are listed below and are also available in a automatically parsable (and updated) form at the bottom of this article.
|Jive Block 1||220.127.116.11/22||255.255.252.0||0.0.3.255|
|Jive Block 2||18.104.22.168/22||255.255.252.0||0.0.3.255|
|Jive Block 3||22.214.171.124/22||255.255.252.0||0.0.3.255|
|Jive Block 4||126.96.36.199/21||255.255.248.0||0.0.7.255|
|Jive Block 5||188.8.131.52/20||255.255.240.0||0.0.15.255|
Our recommendation is to create explicit rules that allow traffic to and from Jive’s IP blocks (LAN→ WAN and WAN→ LAN) and set high in priority — even if this is implicitly stated in another access rules down the list. Be sure that the phones are using a reliable DNS server as a DNS failure can delay or prevent call setup. We strongly recommend using Google’s DNS, 184.108.40.206 and 220.127.116.11.
