Interesting. My ATA is also behind the firewall with port forwarding enabled and SIP-ALG disabled.

I have opend a ticket with VOIPo support, text follows.

I will keep you guys updated when I hear back.

Dave.



Gentlemen,

I seem to have an intermittent issue with outgoing calls. I wasn't too concerned about it until 2 other VOIPo customers posted on the forum with the same issue. Interestingly, 2 of us have the ATA "behind the router" topology, and one has the ATA outside the network.

It seems when calls are made to 2 numbers, one a VOIP number (through Optimum Voice, not VOIPo) and one to a standard POTS number, the former goes directly to voicemail, and the latter drops after one ring. The latter sees the number come up on caller ID, but the call is not completed.

I also noticed a strange behavior recently when my home number calls my work IP phone.

The number comes up twice on the caller ID, as if the call is being served twice. Once correctly, and once as if it were a "ghost" call. Sometimes it completed successfully, sometimes not, as if I have a 50-50 chance.

Not sure if it is helpful, but I have clipped 3 call references, 2 are unsuccessful calls, the 3rd was a call to my work when the number showed up twice on the caller ID.

Any insight into the issue is appreciated, as I suspect you may be hearing this from others as well.

Thanks.
