Hello,

I am having an issue launching CUPC 8.5 in our environment (Windows Server 2008 64bit) and in the logs, we seen an error about ports not being available. I've found where the port is specified for use by CUPC to listen to Cisco Unified Framework on 44442. It looks like the app tries that port first and then increments up by 1 till it finds a port that is available or quits after incementing 9 times (tries a total of 10 ports). I'd like to specify additional tries (maybe up to 50 or 60 rather than just 10) so that it keeps incrementing up to at least port 44500. Just to be clear, I do not want to change the initial port it tries first, just the numbe of times it will increment the port up before it gives up. I could not find anywhere in the config files or registry where this is set but it most definitely appears to do this according to the debug file. Any help is much appreciated. In this clip of the debug below, you can see where it tries the next port up to 44451 and then destroy's the service. What this looks like when you launch the app is it blinks for a split second and then goes away with no errors or anything.

Windows 2008R2 64-bit is not a supported desktop client. I would try Windows 7 first.

Thanks Jason. We have since given up on CUPC and found that Jabber 9.x seems to work well in our environment. To let the cat out of the bag, we were trying to get CUPC to work in a terminal server farm (multiple CUPC sessions per server). Based on our debug, this port limitation seemed to be the only drawback and limited 10 CUPC sessions per server in the farm. All features worked as intended with a typical install, nothing special, other than limiting 10 sessions per server. I know if I stated this though, I would have been immediately shut down that it was not supported in a TS environment. I didn't think about the server 2008 not being supported. So you got me!!! LOL!

Please close this thread unless Cisco is interested in making CUPC work in a terminal services environment (highly unlikely).

Thanks,

Roy
