NO. You should only have one at a time. Its impossible to handle the scenario where you receive say on 2833 and then end up sending an info packet, 2833 packet and the inband of the DTMF... triple DTMF. :)

Is there a possibility to activate all DTMF detection modes (in-band, SIP INFO & RFC 2388) in the same dialplan or maybe in the same extension of the dialplan?
