Allworx Technical Support Forum

Anyone have any experience and/or feedback on utilizing Vitelity for SIP with Allworx? We recently moved one of our client's servers to a Vitelity SIP trunk and I'm seeing intermittent errors on inbound calls:
*** 200 OK timed out (no ACK) on 5901 (dialog 0x3e689d4). Discarding call

It appears to happen 3-4 times a day at most, I haven't been able to pin down a pcap of the issue so it's so intermittent (I'll put in 20 test calls and cannot replicate). I haven't heard any complaints of missed calls from the client or anything but I'm concerned they may be missing some incoming calls.

Has anyone had any issues with the Allworx in firewall mode using a dsl connection with pppoe?

I'm not really sure how that is related. But none of those apply.
