External movi - No audiocall/video

[J_Vansen_S]

Hi all,

Problem Statement

• External Movi calling internal EX90 or CUCM extensions, No audio/video at all

Setup

• VCS Express is placed at the DMZ zone with public IP address that is NOT NAT-ed
• VCS  Express X7.0.2 (0 Non Traversal Calls, 5 Traversal Calls, 50  Registrations, 900 TURN Relays, Expressway, Encryption, FindMe, Starter  Pack)
• CIsco CUCM 8.6
• Both VCS Ex & CUCM has been integrated together for calls to be made to each other successfully(internally)

Please advise what did i had missed in my configuration.

Hi Jocelyn,

Are the necessary ports opened for the external MOVI to send the media. From your description it seems that ports are not opened on firewall for MOVI to send the media.

MOVI uses media port range 21000 to 21900. check the admin guide for more details.

Hi Jocelyn

You can read manual for traversal firewall:

Do you test connection for external device, not movi ?

Very good discussions:
