Hello guys,
First of all, I'm new with VoIP configuration and now encountering VoIP traffic issue while the call flow traverses the Check Point Gateway
I will briefly explain an issue.
1. When Phone device ( 192.168.10.204 ) that behind firewall calls to Phone device that's the opposite side of firewall ( 10.105.62.102 ). RTP message is working fine, both sides can hear each other
2. But If Phone devices from the opposite side call back to 172.19.0.204 ( translation to 192.168.10.204 ),
RTP message is not working properly, only one side can hear voice but another cannot.
In this point, Phone A could hear, but Phone B could not.
Please see diagram below to refer
Does anyone here ever encounter issue like this before?
Really appreciate every comments
Regards,
Sarm
