Is your domain provisioned with the WebEx connect service?

Hi Brian,

Will try what you suggested, but other than this issue I have another symptom, the user must use Jabber for first time from inside the network then afterwards he can use it from outside but if he tries the first time from outside the network it won’t register as all, even the login stage is not passed.

Does this point to anything ?

Try removing "inspect sip" from the global policy.  You don't want that in there with Expressway.  Not sure if XMPP traffic hits that as well or not.

You can also try refreshing the IM&P Servers on the Expressway-C Unified Communications configuration.

Enabling diagnostic logging on the Expressway-E and Expressway-C then trying to connect should help show what is going on as well.

Hi Brian,

Currently I’m opening all IP traffic to Expressway public IP on our Cisco ASA FW

Regarding the inspection configured here it is :
policy-map global_policy
class inspection_default
  inspect dns maximum-length 512
  inspect ftp
  inspect h323 h225
  inspect h323 ras
  inspect rsh
  inspect rtsp
  inspect esmtp
  inspect sqlnet
  inspect skinny
  inspect sunrpc
  inspect xdmcp
  inspect sip
  inspect netbios
  inspect tftp

which one could cause this issue ?

Looks like possible XMPP/TCP 5222 connection issues from the logs.  It just keeps reconnecting over and over again but the port is open on the Expressway and through the firewall.

What model firewall are you using?  You may need to disable some XMPP inspection/application filtering.

Dear Gents,

I have a question regarding Jabber setup, I have Jabber client working fine from internal network but externally it’s able to login and both phone and voice mail services are connected but IM service is not working while IM service works just fine from inside network.

Attached is Jabber client logs for this case.

So any ideas ?
