I have ht-486, PAP2 and x-lite connected to elastix 1.3 (upgraded last night from 1.1-6 for this problem but still no result, it got worse). I have two Dahdi (formerly known as prince opps zap ;-) lines on x100p and multiple outgoing SIP trunks. I have only ulaw and alaw codecs enabled. SIP trunks are exclusively used for outgoing calls. Dahdi is for incoming. All the incoming/outgoing calls, faxes are fine but when I call a number that has IVR and press buttons on my phone, the recipient IVR gets multiple instances of same number. I press 2 they get 2 2 or even 2 2 2. This also happens on outgoing Dahdi! line. I have tried peer setting dtmfmode= to inband, sip info, rfc2833 and auto individually and in combination. I have also tested individual trunks. All fail in same manner. I tried xten connected directly to SIP prover and that seems to work fine. I have also made changes to ht-486 and extension in freepbx to match above setting everytime but that did not help either. 1.1-6 was little better as one sip trunk would work most of times but now dahdi or sip nothing works. Any suggestions?
