Can someone give me a clue as to why I keep hearing DTMF type beeps on my phone calls. It sounds exactly like someone on the other end is pushing a key on their phone but they are not! Has anyone ever heard of this before? It use to happen once in a while, today it's been happening a LOT and it's driving me batty.. -- Start Your Own ISP! http://www.YourOwnISP.com
It's a common problem with VOIP and tends to happen when certain voices hit tones that mirror a DTMF soundwave. Some CPE's may be more sensitive and therefore more likely to cause problems in this regard. -mark On Jan 24, 2005, at 2:38 PM, Me wrote:> Can someone give me a clue as to why I keep hearing DTMF type beeps on > my phone calls.

DTMF can be caused by "talk off". Essentially a voice pattern that triggered the DTMF detection. Now for the part that would have been smart, identifying the location your DTMF is being detected. If it where all zap, then it is the DTMF routines in asterisk/zapata, but as you didn't bother to expound what is going on, it could be SIP hardware phones acting up on you. More details please before you go batty. -- Steven Critchfield <critch@basesys.com>

Seems like a silly question, but sometimes a side effect of having network congestion or hard drive issues will result in beeps or squeaks in the call. If so, here are some things to check. 1. Voip over the internet? Anybody's guess on bandwidth. 2. hdparam -u1 /dev/hda1 -Brett
It could be a number of things... if you are running RFC2833 then some sounds on the line (high-pitched voice?) can be interpreted as DTMF. Also beware of some gateways and using SUB/NOTIFY, had a couple of instances when the DTMF was supposed to be stripped from the in-band (RTP) but wasn't...> -----Original Message----- > From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users- > bounces@lists.digium.com] On Behalf Of Me > Sent: Monday, January 24, 2005 12:39 PM > To: asterisk-users@lists.digium.com > Subject: [Asterisk-Users] Damn DTMF Beeps on my calls > > Can someone give me a clue as to why I keep hearing DTMF type beeps onmy> phone calls.

I get it a lot when I call interstate on my land line.
