Yealink keep several connections open to outbound proxies

[DmitryTsyganov]

Hello,

We have an issue with Yealink phones, which are not terminating TLS connection to outbound proxy after it switched to another one.

Both outbound proxies have same domain name configured, which resolves via DNS record A into several IP addresses. Sometimes Yealink switches to another proxy, and doesn't terminate connection to previous one. Thus we have pretty high connections count.

I did lab test on YL T21PE2.

Please advise.

Thanks,
Denis
