I am using Asterisk on Ubuntu 18.04 and on Debian buster. The network interfaces (for SIP Signaling and RTP) get stuck after sometime (2-3 hours) and need to turn off/on the interfaces to resume the traffic.

H/W: HP Pro. DL380 and Dell PE R730 XD OS: Ubuntu 18.04 and Debian buster SIP Signaling IP: x.x.x.71 and RTP IP: x.x.x.199 communicating with same G/W x.x.x.1.

Have anyone got the similar issue or someone have any suggestion ?

  • what is "stuck"? – user253751 Mar 02 '21 at 09:35
  • Network interfaces stop working and do not pass through the traffic until we turn off/on the interfaces. – Linux User Mar 02 '21 at 16:27
  • Can you verify with tcpdump that they are really stuck while sending pings (ie: not just the SIP traffic)? Are there kernel messages (`dmesg`)? – A.B Mar 02 '21 at 20:30
  • Hi A.B, For the said two interfaces, we are using them specifically for VoIP (Lets say eth1 for SIP and eth2 for RTP/Media). One of the either interfaces stops/stuck, causing disruptions with the respective traffic. Let me verify with the tcpdump and will share the outcomes. I am using a script that pings the SIP and RTP/Media gateway IPs and restart the interface that stops to ping. Have gone through the dmesg but observed nothing in that. – Linux User Mar 15 '21 at 16:05
