DTMF sent from cell phones are usually not well recognized at the asterisk end. The main reason for this is that cell phones transmit out-of-band DTMF, which by the time reaches an asterisk server traveling through cell towers, their equipment, various VoIP carriers etc. is usually drifted away from its acceptable frequency threshhold. Or if a carrier is converting it into inband, it might not be right at this carrier's end, meaningful it'll have no tone at all.
Receiving out-of-band DTMF over physical lines like T1s is usually much more reliable than SIP, because the expensive equipment at big telcos is better at fixing up bad tones and send you the correct tones.

I cannot seem to find an answer or ... Hope this answer is more helpful than harmful, but in my experience and reading, feature codes and cell phones don’t play well together. DTMF processing is usually way less than 100% reliable in this setup. Your best bet is probably to replicate the feature function you want into an extension (1234 instead of *72) and dialing that from your cell or using the web interface on your cell to do the ARI function. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
