Since we applied the VOIPo-VOIPo internal calling fix, the system behaves differently and is not designed for multiple server registrations. Usually this isn't an issue since we provision everything. With that said, today we're going to work on some security measures to prevent users from registering to multiple servers. Going forward, if you are registered to one server, the system will only allow an additional registration (such as softphone) on the same server.

Thanks Tim. It is looking much better now. Was this a BYOD person I assume? If a person uses Asterisk for example, the config should be to only one server (ie central01.voipwelcome.com) I am guessing. Actually in asterisk I don't know how to register to multiple servers with the same service so I hope it wasn't me that broke it!

I have tried from two different cell phones and can not get any calls to complete to my voipo number. No voice mail, no fail over, nothing at all. I can dial out.

EDIT- MWI issue still there and has been escalated to tier 2.
The two calls I made from cell phones both show in vpanel even though the call never rang on anything.

I have you tried any incoming calls to see if they work?

Yes, my incoming calls seem to work fine.

Removed because I am sure Tim will take care of this.

Scott, is your outgoing working? I cannot make calls, but can receive them. I sniffed the traffic and saw my invites being ignored, so the outbound times out. I opened a ticket but was told that they were able to make a call using my credentials so it must be at my end.

Currently no known network issues, if you open a ticket or shoot me a PM I can grab a network trace and see whats going on, thanks!

Everything is working as normal for me. I was having some break up on some calls which is not normal but I believe it is cleared up.

One thing I noticed on my asterisk box, with inbound calls they used to come from a Level3 IP address 4.68.250.xxx and now incoming calls show a 192.168.27 address? I think calls used to be handed off to Level3 and my box would talk to Level3's media gateway directly and now the audio is going through VOIPo's IP's when I look at connections on my firewall. This started around 9:00 this morning.

That's about the time my service went out and apparently caused issues for 1000's of people. They probably made some kind of change when they were trying to figure it out.

Scott,

That 192.168.27 address you are seeing is the local CLEC that is delivering your origination (for that phone number). As for your media path being directed to our gateway, this change has been for quite some time now (since we've had better reports of us handling the audio). This is not a result from any changes this morning.

Are you continuing to see any call quality issues? Please submit a ticket and do let us know if you are so we can further look into this for you.

Thanks!
