Rapid Incoming calls not connecting
If a second call comes in just after a call was hungup (within 20 seconds), there is no audio and call doesn't fully connect.
This is happening on T41p in STUN/TLS mode on 3cx server with latest v80 frimware. Everything else works great. It is very frustrating.



Any ideas?

RE: Rapid Incoming calls not connecting
How many phones do you have?
How many of them have this problem?
Can you help us to get the pcap and syslog and config.bin files. We can check something from them.
You can know how to do from the FAQ: http://support.yealink.com/faq/faqInfo?id=311

RE: Rapid Incoming calls not connecting
We currently have 5 Yealink phones and they all have the problem. (If we can work out this problem we will deploy to the whole company..)
I have attached the PCAP & logs to an email.
Thanks!

RE: Rapid Incoming calls not connecting
Can you please clarify what you want me to do? I should reproduce the scenario again and capture with wireshark instead of directly on the phone? Or do you want me to do something with the files I already sent you. Sorry not understanding...
Regarding the times of the calls. The 3cx log I included will tell you times? Let me know if that helps. Thanks

Sorry I didn't see this post sooner, the email notifications on this forum appear to be broken...

Sorry that I don't receive the infom email, so I don't see this respond immediately. And I need to tell you more detail info. So you can understand what I want.

We check the files. The PCAP files from phone side have limited memory, normallly it's about 200 kb. And you problem about the second call, so the pcap can't capture the message of the second call. So I ask you help us to get the PCAP file via the wiresharl, it don't have the limited memory.

Please help us to get the pcap via wireshark and syslog via phone side.

And please record the time of first call and second call, it will help us to check the file. Just like the 2016.4.6 21:13:50 of first call, 2016.4.6 23:13:50 of second call.

Thank you in advance.
