I am mistaken about ICMP i think.
I think that ICMP is needed for the remote worker.
I do not think yuo need it for this but you can try.
Read this and check:
The Avaya one-x Mobile application must be able to connect from the Internet to the one-X
Portal and to the IP Office system, using either using a 3G network or an external WiFi service.
Your network setup must support this capability.
If the one-X Portal and IP Office will be deployed behind a router or firewall, the following TCP
ports need to be allowed access through the firewall:
• ports 5222 and 8444 must be open in order for the one-X Mobile application to
communicate with the one-X Portal server; port 5222 is for XMPP traffic and port 8444 is
for bootstrap REST API call traffic
• port 5269 needs to be open for the one-X Portal server to be able to federate with another
XMPP server outside the company firewall
In addition, an FQDN that is resolvable over the Internet must be assigned to the public IP
address of the router that is fronting the one-X Portal. That router must be configured to forward
packets destined to ports 5222, 5269 and 8444 to the one-X Portal; you can achieve this by
creating port forwarding rules on the router.
You must ensure that your network meets these requirements before you deploy the one-X
Mobile application.
BAZINGA!
I'm not insane, my mother had me tested!
