I have been trying to get H323 or OOH323 working in Asterisk without success. One thing that is bugging me is this, Below SIP and IAX both show Yes for Devicestate, Indications and Transfer but H323 and OOH323 only show yes for Indications. What does this mean?
*CLI> show channeltypes
Type Description Devicestate Indications Transfer
OOH323 Objective Systems H323 Channel Driver no yes no
SIP Session Initiation Protocol (SIP) yes yes yes
H323 The NuFone Network’s Open H.323 Channel no yes no
IAX2 Inter Asterisk eXchange Driver (Ver 2) yes yes yes
