DTMF Not Sent RFC2833 When Keys Pressed Quickly
I've noticed a problem with DTMF on the T32 when pressing keys quickly or for short durations. The phone itself adds the digit to the display and it plays the DTMF tone. When looking at the RTP stream, that digit isn't sent. I pressed the keys very quickly.

I'm attaching the pcap trace from the phone and a section of log file for this call. You can see that the phone log shows 4736# being recognized and sent. When looking at the pcap trace, you'll see that only 4736 was sent to the phone switch. I can switch to SIP INFO for DTMF, but I'd rather not. Any thoughts?
