<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I have a situation where a caller using IPC 7.0(3) (SCCP) via Cisco VPN is calling an external conference bridge through a PRI gateway connected via SIP trunk to CUCM. The user finds that post-connect, his dtmf is not being received by the far end. I have what appears to be an identically configured IPC 8.6(1), using the same vpn/cucm/gateway which is able to successfully transmit the digits. Does anyone know if there was some kind of fix/change to IPC, or should I be looking more carefully for a config difference on the CUCM/vpn config?<div>
