Yeastar Firewall Rules

Firewall whitelist request on Linkus and IP phone network for PCE service

In sensitive departments of government, banking systems, transaction centres, data centres, where are vulnerable to network attacks, almost network administrators configure restrict policy in firewall to defense attacks. However, we still hope calling services could go on normally, therefore have to allow necessary target servers and ports in firewall. This article lists required servers, protocols and ports for Linkus and IP phone client network where there is internet restriction.

For IM Server, it is dynamic servers and do not have designated IPs and only provides required target ports, only have to allow to access those TCP ports in firewall, ignore those ports if it doesn’t require chat service in Linkus app.
