'Losing' VoIP Provider connection

[CloudBand]

Hello again, all,

Working through the issues ... with the help on this forum.

Next thing is this:

After a period of inactivity incoming calls are not being connected. You get the UK 'unobtainable' signal. I can always make outgoing calls. in fact, making an outgoing call 'resets' the connection and incoming calls are then working ... unless the period of inactivity is long (at the most a couple of hours, though it could be as low as minutes ... you just can't tell, as people can't ring you to tell you your phone system doesn't work!).

My VoIP provider suggested something called 'keep alives' ... but cannot see any reference to them in the management console. I am pretty sure this is a 'duh' moment on my part, but any help would be gratefully received.

Thanks,
CB

Hi,

Could you please specify your VoIP provider?

Thanks
P.S. better to specify incoming invite from provider.

Hi, Sy,

Thanks for helping me out (again!).

Yeah ... its VoIP Unlimited, who are, I believe, one of the supported providers (there is an option for them in the Voip Connection wizard, anyway).

I don't know how to tell the incoming invite from the provider, however i did restart the Phone service, and call from another number, and this is the log (including the restart entries):

Hi CloudBand,

The history of this forum says that I have no chance to help you.
The log you provided is completelly good and you have received the call, isn't it?

VoIP Unlimited - supported provider.
"keep alives" is on place (PBX do it)
The question is how to sort your issue...

NAT... what is your device?
Logs... if PBX does something it logs it.
Network topology?

I know that it is the pain to provide information related to the problem. Sorry, but is the same pain to understand it...

 

[CloudBand]

:lol:

Yeah ... that is the log of a successful incoming call. I included it because I thought it might give you the 'invite' information you were after.

You say 'keep alives is on place'. Not quite sure I know what you mean ... however I have checked the 'Enable Keep Alives' (which was not checked previously) on the Global Options tab on the General Settings screen. See if that has anything to do with it - please advise if you think this is a bad idea.

Regarding Static Mapping. I think I know what this means ... I have, on the firewall, said any traffic that comes in on ports 5060 and 3389 to forward onto 192.168.1.3 (which is the box the 3CX server is running on). That sound okay to you?

My router is a Netgear DG834.

Networking looks like this:

Router (192.168.1.1)
Wireless Access Point (192.168.1.2)
Server (192.168.1.3)

WAP is wired into the router
Server is wired into the router.

2 x Linksys 940's, wired into the router.
A couple of laptop clients, DHCP from the server.

That the kind of info you are looking for?

Thanks again in advance for any insights you can give,

CB

is an answer for

My VoIP provider suggested something called 'keep alives' ...

I've just specified that something called 'keep alives' is always present.

P.S. I didn't mention "Enable Keep Alives" parameter. I told about "refresh of NAT device mappings"

I have no idea about "3389", but
"Static mapping" also means that everything what will be sent by 192.168.1.3:5060 should be sent by your router from <extIP>:5060 to any destination.

I can mention "Full Cone NAT", but I'm not sure it is necessary.

P.S. I believe that Netgear DG834 can do it.

Well ... the problem is no longer there. I will experiment over the coming weekend with the Enable Keep Alives tick box, just to confirm/deny that it was that that fixed it. As far as I am aware no other work on the server has been carried out, and nothing else done on the firewall. At the moment, it isn't broken, so I don't need to fix it.

Really appreciate everyone's input - especially Sy. Thanks as always.
