Intermittently sbc does not respond to clietn hello when using tls

[csadi97]

Describe the bug
We are using Freeswitch 1.10.7-release.13~64bit
We are using tls with our external sbc and intermittently we stop seeing SIP messages coming in
When we looked deeper, I could see the tcp connection being Established but the sbc was not responding to client_hello from the far end [far end sbc engineer confirmed this with a capture from their end]
The problem gets resolved when i restart the freeswitch sbc

To Reproduce
Was able to reproduce by restarting the far end sbc
Essentially all it requires is for the far end sbc to renegotiate the tcp and then tls

Expected behavior
Freeswitch sbc has to respond with a server hello when it gets a client hello and converge

I'm running FS on a different server [FreeSWITCH Version 1.10.1-release.3~64bit (-release.3 64bit)] and i dont see the problem on that

[themsley-voiceflex]

Might be worth trying the patch for #2283 on this as it sounds similar(ish)
