Skype to sfb calls with RPG500

Hello all,

I am using RPG500 registered for SFB online.

When i call from another SFB account the call is OK but when i call the device from a skype account there is only audio,no video at all.

Skype to SFB calls with the same accounts are OK using the classic desktop application,the issue seems to be only when RPG is present.

The device is running 6.1.5 f/w version.

Any ideas?
