Antony, What is your Freeswitch version?

1.10.7 - current Debian package from https://files.freeswitch.org/repo/deb/

uuid_hold in FS 1.8.5 does not send out reINVITE with sendonly.

It turns out from looking at the code that both the command uuid_hold and the dptools:hold application actually call the same underlying function (switch_ivr_hold_uuid) to achieve the holding.

Antony,

For hold FS does not send reINVITE with SDP containing a=sendonly to upstream PBX. You need to change the source code to do that.

Er, yes it does. I now have a working solution.

Thanks to all who helped me in the right direction.
