chan_dahdi.c: !! Not yet handling pre-handle message type USER_INFORMATION (0x20)

ERROR[14110] chan_dahdi.c: !! Don’t know how to pre-handle message type USER_INFORMATION (0x20)

My current setup is.

Please help to resolve this issue
thanks in advance…

If this is an analogue line, or channel associated digital line, contact Sangoma, as the event will be specifically originating in the Sangoma equipment.

If this is a common channel signaling system, please provide details, and also provide a protocol trace of the signaling.

Please note that I don’t have the dahdi knowledge to take this any deeper and the those people here, like Malcolm, who work for Digium, will take the position that Sangoma should be providing the support, here.
