Audio Cut-outs
I’m having an issue with some Snom 300s on a server running Asterisk version 13.9.1, Dahdi 2.11.1 w/OSLEC and pjsip 2.5.1. There is _*NO
NAT*_ involved. Phones and server are plugged into the same network switch, all on the same IP range. The server is running a Wildcard AEX410 analog card with 2 FXO modules receiving incoming analog lines.
Occasionally, in the middle of a call, the audio will drop out for between 15 and 20 seconds before suddenly coming back. I’ve tried running u-Law as the codec and licensed g.729 version 13.0_3.1.7 with exactly the same results. I have tried turning on every logging option I can think of to troubleshoot this but have not been able to find a solution. I’m troubleshooting by remote, so haven’t been able to run a wireshark capture yet.
pings to the phones from the Asterisk server show no packet loss during the cut-outs.
Any ideas?
Thanks,
*Brent Davidson*

I had this recently… and i bet if you use wireshark/tcpdump youll see a dns lookup for the server’s own hostname right before the cutout, and audio again after response is received. quick fix is to add the hosts name and ip to /etc/hosts

I dont know the rules of the mailing list, but im curious if this fixed it for you. I’m just that kind of person. do you have any confirmation?
