Cisco media gateway and DTMF<BR></FONT><BR></DIV>

<DIV style="FONT-FAMILY: Times New Roman; COLOR: #000000; FONT-SIZE: 12pt">Hi
guys, I'm having an issue with DTMF detection from our cisco 5300 gateways.
DTMF detection has been working great when someone was manually inputing
the digits (ie there are small pauses between the DTMF digits), but when
the other end is sending those digits from say a speed dial or programmed dial
string and can send the DTMF digits one right after the other we start to drop
one or more digits about 75% of the time.
<DIV><BR></DIV>
<DIV>I upgraded to trunk this morning and have tried everything that was
listed on http://wiki.freeswitch.org/wiki/RTP_Issues . I have a
pcap output of the SIP and RTP data, it looks fine to me, I can see the DTMF
payloads coming as they should be. Any ideas? I would be fine
sending or posting the pcap file to someone privately.
