Yealink Forums

My business is closed due to the national lockdown here in NZ and I'm trying to get my business phones working from my home office and it's not going so well. Any help for a Yealink newcomer is gratefully appreciated!

Essentially, I believe my ISP/VoIP provider is blocking my outgoing calls from off-network, however, they have said no at 1st level support so I need some ammo to get through to level 4 ideally.

I have a W60B with 1 W56H and a T41S with the DD10 DECT adapter.

The line is registered and receives incoming calls on that line. When I attempt an outgoing call if fails quickly with "Forbidden".

There are other accounts registered on the W60B with a cloud PBX and my home ISP/VoIP working perfectly. I have set up the T41S for this account without the DECT adapter and get the same failure.

At the business office I use a CISCO ATA (SPA112) for this line and have used its settings for the registration on the W60B, with the intention of replacing it with the Yealink setup soon. This ATA device does not work from my home office either.

I have setup a syslog server to trace the call process and can attach here but the key entries I see are:

- a new call is established (call staus update [0]==>[2])
- a packet is successfully sent to the SIP server and a reply received
- a couple more exchanges of packets with the SIP server
- call status changes to 19 (call status update [2]==>[19])
- the call is released <<RELEASE-REASON>> (0xe2)

There is no SIP proxy involved, the connection is UDP only.

I'm sure there are many reasons behind a "forbidden" call failure (it's often as much about what's not in the log) so please let me know if there's another area I can look at, perhaps it's my network setup (NAT?) which is why the ATA I brought home doesn't work either.

Here's a highlight of the syslog output (phone# replace with NN):


Whether making a call or not I also get the occasional DESV<3+error > 792.450.786:get_ip failed ret= -1

I would port my phone number to the cloud PBX but I get an unbeatable package with unlimited free national and mobile calls on 2 lines

Cheers for any assistance

Hi Richard,

Let me sum it up if I understand your issue.
At your business office you use a W60B with two accounts, 1 business and 1 private.
The W56H and T41S are both connected to the W60B.
All work well, no issues.

Because of the lockdown you must work at home, so you take the W60B, W56H and T41S with you and place it in your home office.

Now you have issues… and only with outbound business calls.
No issues with incoming calls, business or private, at all.

I do not think there are issues with you modem/router or other network component at your home, but you can always check if the SIP ALG feature in your modem/router is disabled.
SIP ALG should be a SIP helper but it create more issues than it is doing good.
Also check the port (forward) setting of your business and home router if they are setup different.
Why: SPA112 at the office don’t work… different LAN IP-address and that’s why it cannot communicate with your business VoIP provider?

It is a nasty issue.

Not quite. The Yealink setup is new and not yet deployed so I am trying to get it working from home by registering the main business phone number on the W60B to make/take business calls at home. The Cisco ATA was working at the office and I have brought it home, I can't make calls from home on this either. Both register and can receive calls with audio working in both directions, they just can't initiate calls.

I have 4 other personal SIP accounts with 3 different providers that do work at home on the Yealink setup.

Thanks for the tip on SIP ALG, I have disabled this on the Unifi USG in the controller. This hasn't made a difference yet but I will reboot everything in the morning to see if that changes. This also gives me something to discuss with tech support at my ISP but I don't expect much, on a business package they set me up with a consumer grade Router/WiFi/modem/Firewall (that got hacked within 2 days of going online) and if you're not using that then support kind of halts!

I guess your provider is blocking unknown IP-addresses to avoid unauthorized calls.
They only validated your main office IP-address.

Turns out this is the most likely case, the Yealink phones are now in the office with the only change being the internal IP address and working well.

I was hoping the syslog output of the W60B would include more detail on the response from the SIP proxy like a response code, is that encrypted in the packet received from the proxy or does the proxy even give detail?

There's no support article here to indicate what call status 19 actual means or if it's just a generic response for call failure.

My home ISP is part of the same group of companies as the office ISP and tech support said it shouldn't be a problem. The evidence suggests otherwise - that my home connection is considered off-network.

Thanks for all the replies. Disappointed that my ISP couldn't assist during an event like this but so far liking the Yealink products.
