srst with sccp phones wont pass dtmf

Greetings all,

So I have 2 locations, one boston, one london.  Boston has 1 pub,2 subs for cucm as wel as 2 UC.  London has one UC.  All phones register back to boston.  The trunk to the london UC is sip.  when we ran a SRST test, we could make outbound calls, inbound calls and inter office 4 digit calls. (SRST was working).  When we tried to call the Unity Connection system, the UC answered but was tone deaf.  it heard no DTMF. 

All phones are SCCP

CUCM --> UC trunk is sip.

What needs to change in the vgw to have this work correctly.

Set your DTMF to RTP-NTE.
