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

I see with pass-thru enable EO an DO not workink.
how can I solve this?
Thanks!
Joao
