[cisco-voip] IP Communicator 7.0(3) vs. 8.6(1) - DTMF issue

[Dave Wolgast]

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?

Dtmf-relay on the inbound voip dial-peer is dtmf-relay rtp-nte sip notify.
Codec is g.711mu-law. When the 7.0(3) IPC calls me, I cannot hear the dtmf.
When I call him, he can hear mine.
