CUCM Early Offer to ISP

Hi,

I have one problem to sent EO to ISP.

My scenario:

CUCM 9X -->SIP TRUNK--> CUBE --> ISP SIP

I need invite Early Offer to ISP, for DTMF problems, I don´t like the use CUCM fot this.

I set in CUBE (early-offer forced), but if I removed pass-thru content sdp, I received fas busy and CUCM return Internal Server Error:

voice service voip

no ip address trusted authenticate

address-hiding

mode border-element

media flow-around

allow-connections h323 to h323

allow-connections h323 to sip

allow-connections sip to h323

allow-connections sip to sip

redirect ip2ip

dial-peer voice 2978 voip

description ##  SITE 2978 ##

voice-class codec 1

dtmf-relay rtp-nte

fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback pass-through g711alaw

I see with pass-thru enable EO an DO not workink.
