W52P User Agent different

[Yealink Support]

Hi Antonio,
Any updates?
We tested at our side, but the user agent is the same, as below:
User-Agent: Yealink SIP-W52P 25.30.0.221 00:15:65:40:ad:38
You said it's different, so could you provide the PCAP trace for us reference? And also provide these two different user agent?
"Do you mean when you use http and https to access to your directory, you found from PCAP trace that the User Agent sent from phone is different?
Could you give me an example? "
Thanks.
