Is NAT reflection is configured at firewall ? Or you can analyze pcap in expressway in case of any port block at network.

Hi Ahmed,

Did you opened the port 2222.

As well the ports 36000 / 36001* or 2776 / 2777**

Please refer the firewall configuration guide for port to be open.

http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-7/Cisco-Expressway-IP-Port-Usage-for-Firewall-Traversal-Deployment-Guide-X8-7.pdf

For testing purpose you can check which ports are getting blocked while re creating the issue.

Regards,

Raaj.
