Seems like you might be having a problem establishing media... you may require a transcoder to be configured depending on the regions configured and what the devices support in the way of codecs.

Just throwing it out there but if you have the know-how to run detailed traces do so while attempting to complete the transfer and you should see CallManager search the assigned DP->MRGL (if assigned) for transcoding resources (as Matt said) and then eventually fail and release the call.  If that's the case it's more than likely a transcoding issue.

If you have available DSPs in your head-end gateways make sure they exist in an MRG/L accessible to the DPs of both the phones and trunks (on both sides).
