Cisco 6921 SIP69xx.9-4-1-3 Conference issue

[simonmossman]

Hello all

I have setup 6921's but the conference feature does not work. When I transfer the call it shows as "call ended"

I have changed the busy trigger to 2 and max calls to 4

I have two conference bridges registered with the cucm and the phones have the media resource group list configured on the device. This contains two media resource groups with all resources assigned from both pub and sub.

Exactly what are you doing?? ad-hoc?? meet-me??? Because you mention you "transfer" the call

Sorry, I meant conference....when I press conf key it asks for a number which I enter another extension then pick up. Then I press the conf soft key to bring it in and I get the "call ended" message
