Does anyone knows if MCU 3515 supports direct ip dialling? we want to establish videoconferences but participants should be able to dial to an IP address without registering to a gatekeeper.

Yes it wil support. When you enable SCCP on the MCU you are only able to use one service in conjuction with either ad-hoc or meet-me video telephony conferences. For example the default SCCP service prefix of 70 in the MCU would be used by CCM to initiate either conference type.

Direct IP dialing is supported on MCU 3515 only in version 5.6. In order to do so, you have to do the following :

- Put a fake gatekeeper address (if you don't have any gatekeeper) i.e. (do not use an ip address ending with 0).

- Enable Auto Attendant IVR

- Choose a Default Service Prefix previously configured as Service Type : "HD/SD Continuous Presence".

- Disable "Register conference ID" on Advanced Settings.

Now you can Dial through the MCU IP address.
