ok guys, here it is. The final answer. After going through the CUE config, we noticed that the IP address on the CCN Subsystem SIP was wrong. ccn subsystem sip gateway address "10.1.1.1" dtmf-relay sip-notify end subsystem the IP should have been 10.1.10.2 interface Integrated-Service-Engine0/0 description cue is initialized with default IMAP group ip unnumbered Loopback0 ip nat inside ip virtual-reassembly in service-module ip address 10.1.10.1 255.255.255.252 service-module ip default-gateway 10.1.10.2 after changing this, the system has worked so far. Crazy thing is, this has been like this since the beginning of the year when cisco tac helped us to rebuild the CUE when it went down before. Anyway, seems to be fixed now, I hope. I will keep you posted if it changes. thanks for all your help. ... View more

I have noticed a few mentions about IMAP in the config. ... View more

Hi Daniel, thanks for the response. I have done the reboot a few times already and it keeps coming back. I am looking into the firmware, however, it was recently upgrade a few months ago. This client is not using the IMAP feature. it appears to be as if there are to many people on at the same time. However their call volume has not really changed. I will post some config info and some debug, however, I am logging in remotely so it is hard to simulate when no one is there. thanks again. ... View more

wow, roger. First of all, I already expressed my thanks, so your claim about abscence of appreciation is actually insulting to me. Secondly, Allan was simply agreeing with Chris, therefore I decided to give Chris the points since he did answer the question for me and finally , had I known I could have given points to both , I may have, but didn't realize anyone could just post points on a blog that wasn't even theirs,  No offense Allan, as I said, I had already thanked you. ...
