I was looking into sending custom sip info messages a while back (but not for fxo hook flash) and found two ways in fs: 1) send_info dialplan app - with this one you can't change the mime type (it's always "freeswitch/data") and you have to set the channel var fs_send_unsupported_info=true beforehand if the other end isn't freeswitch. It's probably useless to you. 2) uuid_send_info api command - this let's you set mime type/subtype so it could work for your case: uuid_send_info <uuid> application hook-flash some_data On 31 December 2014 at 09:43, davy van de moere <davy.van.de.moere@gmail.com> wrote:

Gents,

Does any one have a good setup to send a flash hook to an analogue line? Preferably with an ATA of some sort.

So far I've been trying with an Linksys SPA3102, which can do a flash hook with the specific mime type : application/hook-flash , with Freeswitch I the send_dtmf didn't get me any further than sending the special flash key F in application/dtmf-relay. Which is not interpreted by the SPA3102 as a flash hook.

Hence, does anyone have a good strategy from a Freeswitch pov to send a flash hook signal (do I need to think sipsak?), or an ATA/firmware which does support the F key in dtmf?

Season grtz! Davy
