Call Transfer from H.323 device

I am sending a call to an IP-IVR (non-Cisco) which requires transfer to a CallManager SCCP phone after treatment.

Here is our current configuration:

MGCP-controlled PRI on Cisco 3845 ISR, with CallManager 4.1(3). IVR is configured as an H.323 Gateway with route patterns/route groups/route lists appropriately configured to get calls to the IVR. We are not using gatekeepers.

I can set the H.323 transfer method in the IVR to either hookflash, H.450.2, H.450 Join, or MediaRedirect.

It is my understanding that CallManager doesn't support the H.450.2 method.

Any suggestion for getting this done?

Thanks!

Re: Call Transfer from H.323 device

Correct CallManager supports Empty Capabilities Set (ECS) not H.450.

Media Termination Point Required option in H323 GW config in CCMAdmin is needed if the H.323 clients and H323 devices do not support the H.245 Empty Capabilities Set.
