In-call DTMF

Hello I am having a real difficult time getting in-call DTMF to work. I have a SIP ATA with 2 lines, The device does not have any hook/flash setting to allow xfers. I want to be able to park or xfer the call to pick up on another extension and I have set the debug level to show DTMF on the CLI. I do see the dtmf events but what shows is

[Feb 14 06:52:34] DTMF[8030]: channel.c:4060 __ast_read: DTMF end ‘#’ received on SIP/102-00000030, duration 250 ms
[Feb 14 06:52:34] DTMF[8030]: channel.c:4086 __ast_read: DTMF begin emulation of ‘#’ with duration 250 queued on SIP/102-00000030
[Feb 14 06:52:34] DTMF[8030]: channel.c:4178 __ast_read: DTMF end emulation of ‘#’ queued on SIP/102-00000030
[Feb 14 06:52:35] DTMF[8030]: channel.c:4060 __ast_read: DTMF end ‘9’ received on SIP/102-00000030, duration 250 ms

And nothing happens but if i am not on a call I can use call pickup *8

I think the issue is I can not find a real working example of how to enable this. I have this in my extensions.conf

;Incoming
[from-callcentric]
exten => s,1,set(__DYNAMIC_FEATURES=home-feat)
exten => s,n,Dial(SIP/101&SIP/102)

But how do I put the actual feature under this in features.conf?
