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||188.8.131.52/22||255.255.252.0||0.0.3.255|
|Jive Block 2||184.108.40.206/22||255.255.252.0||0.0.3.255|
|Jive Block 3||220.127.116.11/22||255.255.252.0||0.0.3.255|
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, 18.104.22.168 and 22.214.171.124.
