Exactly. I've had the same setup for almost 3 years w/ no issues then suddenly lots of dropped/dead air calls on Wednesday and a few last week. No ISP problems w/ only 19ms latency to sip-central01. I reset the ATA and my router multiple times to no avail. All of the required UDP ports were already forwarded. About 50% of my calls on Wednesday were affected including Voipo to Voipo calls. Last week, I had 3 consecutive incoming cell phones calls that went to dead air when answered. It was only on the 4th try did it answer correctly. I opened a support ticket on this issue and they couldn't see anything wrong. Very strange things going on recently.......
Tim,
I did not open a support ticket because I'm 99% sure the problem was not on my side. Calls seem to be okay today, but will open a ticket if the issue resumes again. It may have something to do with what the poster "patoka" said below in another thread about networklayer/softlayer having dropouts. Hopefully their issues are being looked at or have been resolved already.
