I have met some problems with jabber remote access.the internal jabber access is ok.but my jabber cannot login from internet.from jabber client message is that"cannot communicate with server",but if i enter userame based on uri format,will reply message"username or password is not correct." Because don't have any troubleshooting tools,I don't know where is the problem.
1、what's problem with this info?
in unified communication>im and presence&unified communication tab,the tcp status are all active,and I select off for TLS Verifiy mode on both.
2、Is that cucm and imp server must have the CA issused certification?I just have changed the expressway c&e cert.
I think CA issued cert just used for expressway & cucm &imp authentication,not for jabber client,because you can accept any incorrect cert when you login jabber.
Now I use non tls verify mode for expressway to cucm&imp sip trunk,and status is active.when I set this mode on,It will pop up message "Failed: Cannot connect to cucm&imp. TLS certificate validation failed."
