Voip Unlimited losing registration

Tim, just out of interest, are you using a selection of firewalls or do you try and stick to one specific device you know works well. I'm currently routing in over a single netgear bridge and straight onto a spare NIC in the server but I want to try and implement some sort of failover and I want to use a router to do this - I'm thinking the Draytek kit may be worthwhile. Our main firewall is a Sonicwall but I've had my fill of trying to get that working with SIP - too clever for it's own good. Thanks in advance. Dom.
 
I have had the same issue with Voip-unlimited. All of a sudden yesterday my 3CX system (v7.1.7139.0) wouldn't allow inbound/outbound calls. There were loads of "CM504005 Registration failed, Cause 408 Request Timeout; internal" messages. The server was working fine earlier in the morning but stopped working around lunchtime and we had not touched anything so it wasn't anything that we had done. I had an account with VOIPON that we used for testing so we put that in as a voip provider and setup an outbound rule to prefix the calls with 9. That worked perfectly inbound and outbound so that proved that there was nothing wrong with our firewall. I rebooted the server and it came back ok and then a few minutes later it stopped working again. This morning I have the same issue - working and then not working. I am now playing with the "time between registration attempts" and "enable keep alives"

This is an example of what happens. Notice how the registration was refreshed at 17:26:46.703 and yet seconds later when a call is made it fails with a "408 Request Tiemout; internal" message.

Hi,

Sorry to hijack an old thread, but the last 2 weeks has seen this happen quite a lot on our system.

(Registration failed for: 10000@VOIP-Unlimited; Cause: 401 Unauthorized)

Has anyone else been hit by this - which might indicate a provider issue?

Regards,

Harv
 
Well, since you mention it, yes -- but with a different provider. Occasionally I get a first response that is 401 Unauthorized, and the second request is successful.

Unfortunately we also have another issue, with the provider not sending any "expires" indication in response to a registration request (and with 3cx not sending re-registers), so I can not tell you whether these 401 are just glitches that do not impact operations or are part of the problem we are experiencing.
 
We have also seen this problem and not the best of pleased with the responses from the support stuff at VoIP Unlimited.
We have a 27 user install of 3CX used by a team of Solicitors who are having major issues, and the provider is 8| VoIP Unlimited.
We are now in the process of moving them to our SIP Services which not only is more reliable but offer more features in terms of fall over should 3CX or the Internet connection go down, we can then reroute their calls automatically, something which VoIP Unlimited does not support.

we had an issue last week with outgoing caller ID not working on 3CX, i could see in the logs that 3CX was sending the info over to VoIP Unlimited but then not being passed on to the caller.
Turns out that a change to 3CX VoIP Unlimited VoIP Template had to be changed, and this issue effects everyone running 3CX V10 using VoIP Unlimited - however their support was very poor and was not getting anywhere.

Mark at VoIP Unlimited was saying we needed to configure 3CX in a certain way, sent us their VoIP Configuration guide, however it did not match to what Mark was telling me on the phone.

Cutting the story short, William England of 3CX found a solution to the problem and was passed to VoIP Unlimited so they could update their configuration guides.

No I’m not a big fan of theirs at the moment. Not forgetting a number of disputes we have had with them over admin work.
Customer wanted ADSL Services, VoIP Unlimited was tasked with the job and installed ADSL, 2 months down the line the customer needed to change phone line providers, to get a better deal, I spoke to VoIP Unlimited about this and was told to get another ADSL put on the customer’s new line and they would stop the other connection.

So we followed the advice of VoIP Unlimited and had the other connection installed, and then contacted them to ask for the other connection to be cancelled. i was then told the customer would need to pay a cease fee of £35
If we had been told this, I would have done a merge and not a new install.

After speaking to a few of the top guys at VoIP Unlimited they saw sense and agreed to not charge the customer the £35 cease fee.

For the above reasons, i am not even passing any more clients their way; we can’t provide a quality of service if the provider lets us down etc.
