I have a VPN phones configured to use a trused relay point in order to provide connectivity to other VPN phones.
 
One of the phones gets fast busy and traces show MTP allocation failure.  This was the only phone trying ot utilize this MTP and is identical to other VPN phones that work as expected.
 
Any ideas?
 
 
Thanks!
