WeChat voice problem on fortigate 60E

[dodie]

Hello Everyone,

We're using wechat as common communication and this has been added as "allow" on my fortigate 60E firewall. This was working before but after wechat upgrade to new version, I encounter voice issues, when I tried calling users via wechat and company network I encounter connecting issues but when me and my users use mobile data, wechat calls can get thru.

Please advice what seems to be the issue on my forti that needs to adjust.

Regards,

Dodie
