[asterisk-users] Transfering not working - how to debug?

[Rizwan Hisham]

Both end devices should be using same codecs. set dtmf = rfc2833 and set
canreinvite = no in sip.conf for both endpoints. This should solve the
problem.  you should also check which codecs support rfc2833 for dtmf and
use that codec.
