Cisco Expressway MRA Deployment-Single Firewall

[Daniov1]

Hello.

In my eviroment I have ExpressWay for MRA

Internet>>EXP-E>>EXP-C>>Cisco UC

All the users in the organization trying to connect to jabber by MRA.

After the user logged in to Jabber for mobile(I see in CUCM the device is in Register mode)

In the mobile the UCServices write "Cannot connect to Cisco Unified Communication Manager Server, Check your network setting".

The firewall isnt blocking ports.

The status in unified communication is active, The traversal zone is active and the cucm as well.

Inside my organization(Lan) the jabber is working well.

Thanks

So, it shows as registered in CUCM but not on Jabber?

What happens if you call from/to the device?

What troubleshooting have you done so far?

thank you for responding.
1.yes that right, it shows as registered in CUCM but not on mobile, In mobile the voice mail and IM are working but the UCServives isnt.
2.I cant call from the device because the jabber not registered with UCServices. And I nor recive a call to MRA.
3.I have cheked the firewall,Configuration on EXP-C and EXP-E.
I have tried to collect logs from EXP-C while login capture and I saw there is a problem between EXP-C in port range 350101 - 350353 ( their is no firewall between of them).
