I am trying to enable TRANSFER for DAHDI in my chan_dahdi.conf file but I’m still getting this…

That output displays static characteristics of the channel drier and in the case of transfer, it relates to whether or not the Transfer dialplan application is supported, i.e. whether it is possible to get the remote side to transfer the call so as to completely remove Asterisk from it.

transfer in chan_dahdi.conf relates to the ability to honour transfer requests arriving over the wire, which would result in a reconfiguration of the call within Asterisk, without affecting the remote system.

Which of these are you trying to do?

Working on the first option… I see in the libss7 that RLT is supported with the Nortel DMS. I have incoming calls from the DMS via DAHDI that we want to release back to the DMS. I’ve been looking into trying to make changes to the code to get this working.
