Solved No Service

[canden]

Hello,

We are demoing (or trying to demo) the Google hosted 3CX using Yealink phones. I've followed the various deployment documents. After a factory reset the phones autoprovision ok as in they connect using the extension and PIN ok - they say they are downloading the config and they pull down all the settings as far as I can tell. The 3CX PBook lists the extensions, but the phone shows "No Service".

When trying to make a call the phone shows "Account Is Invalid!". When I use a softphone on my iPhone on the same subnet I am able to connect to the hosted PBX and the phone shows as "On Hook", however, as soon as I try to make an outbound call it says "not found" on the screen and beeps a few times then disconnects the call.

The only thing I'm uncertain about is the SIP trunk in the PBX. It does show as connected in green and the trunk shows as registered on the SIP provider's side, but it is a generic SIP trunk. I am using the same SIP provider with on-premise 3CX Windows based systems with no problems.

Any help would be greatly appreciated.

So first of all provisioning and registration are two separate things. In your case it appears the phones provision properly since they get the settings and the 3CX Phone Book but they don't register, hence the no service. So things to check are if the extension is allows to register outside the LAN and if the IP is blacklisted.

As far as the outbound call on the soft phone it sounds like either your outbound rules are not configured properly (or at all) or your trunk doesn't like what you are sending. You'll want to check the activity log as errors on the phone/softphone are basic end user messages and won't tell you where to look.

I'm not sure what to say about your SIP trunk question since I'm just as uncertain as you with information you provided. If it is a registration-based trunk and it says registered you should be good. If it an IP authenticated trunk then it will always show green/registered. Typically the only configuration needed is to register the IP address or hostname of the PBX with the provider so it knows where to send calls to and where to expect calls from.

You are awesome! Register outside LAN was turned off - I can't believe I didn't see (or remember that). Thank you thank you.
