Remote extension unable to connect with UDP

[Saif]

Hi all,

I am having an issue with my remote extension. Currently my FusionPBX set in behind nat with a static IP address and I am using Zoiper soft phone to connect with the server. I did open the ports 5060-5090 TCP/UDP and also 16384-32768 UDP port in my router and also disable SIP ALG on my router firewall. If i try with TCP i am able to connect and make calls but when i switch to UDP the (Request time out 408) in zoiper but i dont see any activity in fs_cli even i have stopped fail2ban service. what could be the issue?

Thanks for helping.

sngrep and have a look, also, why not just use TCP? Its generally much better, particularly for softphones.

Hi Daz,

Thanks for your reply i did try netstat -lnp | grep 5060 and found below result:

tcp 0 0 192.168.0.107:5060 0.0.0.0:* LISTEN 703/freeswitch
tcp6 0 0 ::1:5060 :::* LISTEN 703/freeswitch
udp 0 0 192.168.0.107:5060 0.0.0.0:* 703/freeswitch
udp6 0 0 ::1:5060 :::* 703/freeswitch

where i dont see UDP listening. Any idea what could be the issue?. Thanks again.

Hi Daz, Sorry didnt get this is that UDP is listening ? if yes why i cant get register using UDP transport?
