CTI communication (United Kingdom)

Hi All,

We have a Terminal services cluster using SwyxIt in CTI mode. On 4 of the 5 servers everything is working fine however on one of them none of the users cannot connect the SwyxIt to the phones. The Accept CTI message comes up on the L420 but noting happens when you press the tick key. I have check DNS IP connectivity and fire walls and it would seem that everything can see everything else.

How does the CTI handshaking work? this may help me figure out where the problem is. What other tests can i do?

Thanks

Nathan

The handshake is a client to client communication. Enable client and phonemanager tracing. That might give you a clue.

I am not sure if that is true, Tom. The Dialer mode for the S315 phone is client to client (based on SIP). But I am pretty sure that the CTI is controlled server side. This means that SwyxIt! needs to see the server and the controlled L4xx/5xx SwyxPhone must see the server, but they do not need to see each other.

Hi ,

I will open a support request, we do use NLB access all of the servers and it is only a problem on one of them. Strange.

Thanks for all your help.
