[Asterisk-Users] SIP-DTMF

Hi,

I have mapped a number in the default context of my dialplan. When someone dials that number, it
plays an IVR message and allows the caller to enter 4 digit extensions. If the extension is a
valid one, the call wll be routed to that particular extension. 'INFO' is set as the dtmf mode.
This works fine if i call from a SIP UAC which sends dtmf as INFO. But When i dial using SJPhone,
call doesn't get routed, because SJPhone uses inband dtmf. So, my problem is only people who use
UACs that send dtmf using the INFO method can reach the desired extension, where as people who use
SJPhone cannot do this. Can i make Asterisk to receive both info and inband dtmf for the same
number? Is this possible? If so, can anyone tell me how to do that? 

Thanks, Girish
