I've been running an Asterisk server (1.6.2.17.2) for over a year without any major issues. All of a sudden people are unable to login to their voicemail because Asterisk is seeing DTMF twice for each digit the caller pushes. We've noticed the problem only consistently happens to callers from specific locations. All the locations having the issue use te same ITSP and internet provider. The ITSP swears it's not them because they tested outside their phone system, straight from a d-mark. We've tinkered and played with all options in Asterisk related to DTMF with no success. Aside from upgrading Asterisk, I'm at a loss as to how to fix this. This system has worked for over a year without this issue and all of a sudden it appears. My thought is that it's the internet provider (Earthlink) but they say it can not possibly be them. Here is my DTMF settings in sip.conf: dtmfmode=rfc2833 relaxdtmf=yes Any input appreciated! Thanks.
Hi, Not exactly a solution, but I'm sure you must've taken pcap traces of a few such sample calls. See in their RTPs that you are receiving repeatedly same RTPs which will tell you that any DTMF packet is coming in twice by the source or not ! just one such simple pcap will help you identify at whose end the issue lies. If the source is your vendor sending you RTPs twice for DTMFs then send them the capture and ask them to fix it however they can.

Any ideas? On Thu, Oct 11, 2012 at 2:32 PM, Vik Killa <vipkilla at gmail.com> wrote:> Call was to 7167436110 >
Well like I said before and you increased my doubt as well by saying that this happens from callers using E-link internet. Can you share the trace !
