Yealink Forums

Hello Forum,

my phone shows a strange behavior. I configured two accounts in it.
They register without any problem and I can use the phone as designed.
But: when the internet connections drops once a day only one account can register. The other account can not register anymore.

I used a packet capture tool and I see some strange traffic:
First I see the account which can register:
REGISTER sip:tel.t-online.de SIP/2.0

But the other account looks like this:

As you can see the authorization part is missing.

This only happens when the internet connection drops. If the router reboots everything works fine for both accounts.

Any idea?

Hi Matthias ,

The first account use the User-Agent: Linksys/SPA8000-6.1.12

The other account use the User-Agent: Yealink SIP-T46G 28.72.0.26

Do you register them in T46G all?
If this issue happens in other phones when the internet connection drops, please check your network connection firstly.

Here is the right excerpt from the log file. Sorry for sending the wrong one but I have many of the file to track down the traffic and error.

The Linksys was for testing purpose. this one has no issues when the line drops.
Both account are registered in the Yealink phone. The line works perfect.

Hi Matthias,

It is strange of your issue. In order to do more troubleshootings, please supply syslog level 6, config.bin and pcap and send to support@yealink.com , support.usa@yealink.com or your distributor.

How to Get the Correct Syslog, Config.bin and Trace

Did you resolve this issue?
I've had it too and found a fix. In my case, I set the RPORT setting to 1. There is an RPORT setting for each account.
Once I did that, all accounts would register every time.
I've made it a part of my auto-provison config.

#It enables or disables NAT Rport feature for account X.0-Disabled,1-Enabled
#The default value is 0
account.1.nat.rport = 1

I hope that helps you.

Hi,

thank you for the tip.
I tried it right now but it isn't changing anything. I rebooted the phone, nothing changed.

Only if I reboot the router it works. But this is working even without the changes.

Any other idea? Have you changed some time variables for subscribing?
