I've got a problem with DTMF, again. My asterisk box is connected with the outside world (PSTN) via a sip proxy. The problem is that for some reason, I need to use rfc2833 for signaling digits to the gateway and inband to accept digits from outside (eg. when someone dials one of our DIDs). It's possible to do this? I've ever tried splitting 'peer' and 'user' part in sip.conf, but that seems to give weird results... Someone has ever done something similar (or maybe knows how to?) TIA, Simone.
Hi, I'm struggling a bit with DTMF. It seems to work fine on my internal network, but when I call outside lines with telephone trees, some systems understand the DTMF and some ignore it. Anyone have tips on solving this? Thanks in advance. My local phone is a Grandstream GXP-200 mailbox=89 username=89 secret=xxxxx type=friend host=dynamic context=internal-forio dtmfmode=info canreinvite=no And my provider is BroadVoice host=sip.broadvoice.com fromdomain=sip.broadvoice.com fromuser=4153730175 secret=xxxx username=4153730175 authname=4153730175 type=peer user=phone context=inbound-forio insecure=very canreinvite=no -- Forio Business Simulations Will Glass-Husain wglass@forio.com forio.com -------------- next part -------------- An HTML attachment was scrubbed...

Hi Will, You should use the standard rfc2833 as suggested. Also be aware that using "ulaw" will always switch to "inband" DTMF mode, but the phone and Asterisk should automagically detect this. Btw: Cellphones and DTMF just doesn't work well together. If the cellphone is in a poor reception area, it might not send DTMF tones correctly. -- Bjorn ________________________________ From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Will Glass-Husain Sent: Wednesday, March 22, 2006 5:47 PM To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] problems with DTMF Hi, I'm struggling a bit with DTMF.
