[Asterisk-Users] OT: DTMF issues with Vonage forwarded lines

[C F]

Since Thursday (Aug/4/2005) my Vonage line that is fowrwarded (not
even using their ATA) to a number that rings to a PRI that is
connected to asterisk stop passing on DTMF, anybody having this issue?
When calling directly the asterisk box, or forwarding any other lines,
there are no problems. Just the Vonage line has this problem.
