Lync 2010 and RMX 2000 integration "sip tls : registration handshake failure (cs id 1)"

Hi all,

 

I'm trying to do an integration between RMX (7.8.0.246) with Lync 2010.

I followed Polycom documents and I already did others integrations which working well.

 

This is the error I have on the RMX : "sip tls : registration handshake failure (cs id 1)"

 

I think there is a problem with the certificate but I don't see what. Certificate is a pfx created from IIS on Lync Server and his name is the FQDN of the RMX so I think that everything is correctly configured.

 

Have you ever had this problem ?

 

Thank's for your help.

 

Ivan B.

Ivan,

 

Make sure the common name in the certificate refers to a DNS name which resolves to the RMX signalling IP address. Also make sure the Lync Front End servers have the same root CA certificate as you have in the RMX pfx loaded into the Trusted Root computer store and not the user store.

 

Other than having the certificate 2048 bit and Binary encoded.. You should be good.

Hello Simons,

 

My certificat was good. In fact the problem coming from their Checkpoint Firewall where some ports were blocked.

 

Everything is ok now :).

Hello Ivan,

 

Thank you for this answer, do you know which port was blocked?

I have probably the same issue.

 

Thank you
