[Spce-user] SIP INFO for DTMF

Im having issues with DTMF from one provider that appears to use SIP INFO for DTMF.  Ive been trying to find out the cause, and it seems that below is the actual sip conversation that takes place, but ends in Method not allowed here error. 
I thought it would pass thru the SIP INFO to the ATA but from the trace below it never gets to the ATA?  This provider does not use RFC2833.

IF I register the ATA directly to the peer, DTMF works via SIP INFO.  
Any thoughts?
Thanks
Dave
