Known Issues

Issue: Fortigate blocks packets from remote W01FXS/W02FXS; since WMS v. 3.84 remote W01FXS / W02FXS use a new type of SIP encryption with the aim of improving security and bypassing SIP-ALG; Fortigate VoIP security module blocks the packets because SIP requests can’t be identified
Solution: apply the following CLI to disable this issue on Fortigate side:
config voip profile
edit “default”
set comment “Default VoIP profile.”
config sip
set block-unknown disable
end
next
end
