one-way audio

[marceloab]

Good day for everybody. I have the following topology: AvayaS8300/MEdiaGateway => Firewall Fortigate => PSTN incoming calls works fine, two-way audio, hold, conference, everything fine. when I make call and put on hold the outside customer in pstn don´t listen music. and if I try conference, the outside dont listen, but inside extensions listen. I´m using H.323 Softphone and SIP trunk to service provider. So, H.323 station => S8300/G450 => SIP TLS => SES(SIP SERVER) => SIP UDP => PSTN Exten XXXX(10.X.X.X) => S8300(10.X.X.35) => G450 (10.X.X.36) = SES (10.X.X.35) = PSTN (200.X.X.X) My Fortigate config: 60C v4.0,build0458,110627 (MR3 Patch 1) edit 10 set srcintf " wan1" set dstintf " TrunkCisco" set srcaddr " VoipCTBC" set dstaddr " EntradaCTBC_VIP" set action accept set schedule " always" set service " ANY" set logtraffic enable set nat enable next edit 16 set srcintf " TrunkCisco" set dstintf " wan1" set srcaddr " Avaya_S8300" set dstaddr " VoipCTBC" set action accept set schedule " always" set service " ANY" set logtraffic enable set nat enable next edit " VoipCTBC" set associated-interface " wan1" set subnet 200.170.136.197 255.255.255.255 next edit " Avaya_S8300" set associated-interface " TrunkCisco" set subnet 10.19.8.35 255.255.255.255 config firewall vip edit " EntradaCTBC_VIP" set extip 200.233.210.145 set extintf " wan1" set portforward enable set mappedip 10.19.8.35 set protocol udp set extport 5060-65535 set mappedport 5060-65535 next end .

Hi, If you have any one way audio issue over FortiGate, please try following configurations on FortiGate: config system session-helper show edit 20 set name sip set port 5060 set protocol 17 next delete 20 end config system settings set sip-helper disable set sip-nat-trace disable end config firewall address edit " all" next end config voip profile edit " voip_1" config sip set hosted-nat-traversal enable set hnt-restrict-source-ip enable end next end config firewall policy edit 1 set srcintf " internal" set dstintf " wan1" set srcaddr " all" set dstaddr " all" set action accept set utm-status enable set schedule " always" set service " ANY" set voip-profile " voip_1" set nat enable next edit 2 set srcintf " wan1" set dstintf " internal" set srcaddr " all" set dstaddr " all" set action accept set utm-status enable set schedule " always" set service " ANY" set voip-profile " voip_1" set nat enable next end Thanks, Wenlong Qin

Hi, is needed reboot firewall in order to validate configurations? I tried this without reboot, but didn´t worked. thanks

I think it is not FortiGate problem. You may need to check your SIP Server setting to make sure your SIP Server has hold function to work with PSTN phone. Maybe your SIP Server hold function (Re-Invite) can only work with SIP phone.
