I have recently ran into some router issues, but this is happening randomly to one of my customers, Everything is working fine the majority of the time, but on some calls we drop them for up to 30 seconds. The person on the other end can here us so we have to say hold on till we can get the call back. This is in the middle of the phone conversation once the call has already been connected. During this time they are not able to here them on the other end. I guess I can run a sip debug but it happens at random and the file would get pretty big pretty quick. has anyone had a similar issue.
