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

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
no vad
I see with pass-thru enable EO an DO not workink.
how can I solve this?
Thanks!

Why are you using media flow around?

Hi,
I have several sites using the same cube and ISP.
We using flow around to IP Phones, for rtp stream setup direct the ISP SBC.
