My Unity and CUCM (11.5) are intergated using SSCP protocol. It was running form last few months but now I am facing an issue, Unity extensions are not reachable.
I started Tshoot and didn't find any changes in the configuration and testing a "Port Group" is failed and error as below
" Failure reason: ErrorCannotEstablishWinsockConnection. connectToServer(10.10.x.xxx:2000)->0x80045A03"
Looking urgent help for the same.

Thanks for the reply. I didn't find any root cause for this issue but It is resolved after restarting the Unity.
I am happy but not sure why it happened. I checked all the configuration and it was ok.

Are the CUCM servers reachable from CUC?
Are the port names the same on both sides?
Why not use SIP, so much easier?
Thanks for your reply.

Ans: Yes. It is the same
