I don't see any connection attempts on port 5222 in the logs.  Might want to 
enable tcpdump on the Diagnostic Logging page and try again.

Also try https://cway.cisco.com/tools/CollaborationSolutionsAnalyzer/ and go to 
CollabEdge validator.  It will test against your domain with a 
username/password.  You can also put the logs in there and it may show you what 
is going on as well.

Hi Brian,

Under presence there is only one domain and all my servers are in the same 
domain which is the same internally and externally, we just have some users 
accounts on a different domain that’s why I added that domain just to EXP-E and 
added it’s related SRV records.

Please have a look on the attached logs taken from both Expressway C and E for 
a client which works fine from internal network then connected successfully 
from outside but the IM service is not working from outside.

I really do appreciate if you can hint me about possible reasons that make IM 
service not working from outside company network.

In IM&Presence under Presence->Domains, do you have multiple domains listed?  
Do you have something other than default under Presence Advanced configuration 
for setting domain names?  Setting the voice services domain is one of the few 
reasons you need to login internally first.

If you are using UserID@Default Domain then you shouldn't need to login 
internally first.  You may just need to remove the domain portion from the 
username on the username/password page when logging in the first time.

What’s the flexible Jabber ID? Also I have local users created on CUCM with no 
LDAP integration.

For the domain portion it’s not removed if the first login is through MRA and 
the login failed but as mentioned if I logged in thought inside network before 
the login through MRA goes smooth and login successfully but with one exception 
that IM service is not available.

Are you using flexible Jabber ID?

One thing to make sure is that first time MRA login gets rid of the domain 
portion in the username on the username/password form after entering 
username@domain in the service discovery window.

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 ?
