Connection Establishment with FortiVoice Behind Firewall

Hello Community,

 

I have an issue with achieving active connection to FortiVoice located behind FortiGate Firewall using FortiFone,

 

Below you can see the diagnostic report from FortiFone,

On FortiGate side, I created two vip rules forwarding traffic to FortiVoice, as shown below. Notice that I have 0 hits

Then I grouped these rules under “VIP-Group”.

 

And regarding the firewall policy I have created two policies as shown in image below, one to allow traffic forwarded from VIPs and one to allow internet access on FortiVoice.

I appreciate your guidance regarding this matter.

Maybe see Configuring FortiGate for SIP over TCP or UDP | FortiVoice 7.2.1 | Fortinet Document Library and have you added the FortiVoice to the FortiFabric Configuring FortiVoice | FortiGate / FortiOS 7.6.3 | Fortinet Document Library

 

See also:

SIP ALG and SIP session helper | FortiGate / FortiOS 7.6.3 | Fortinet Document Library 

 

 

Test without a VOIP profile as it causes issues sometimes and it is just a Rate Limiter for SIP and SCCP:
