asterisk users - Dec 2005 - Sending Polarity/DTMF Caller ID in chan_zap (Sweden etc...)

Hi,

I have been running Asterisk in Sweden for almoast 7 months now, with a TDM400P
FXO/FXS card.

Two things have been enoying though:
1. Asterisk did not hung up correctly 
	Solved with Asterisk 1.2.0 and patch from issue 0003874 (answer and hungup on
polarity switch Fix )
	Thank you julianjm!

2. Caller id does not work for my Swedish analog phones connected to the TDM400P
FXS modules.
	There is a issues open and then closed 0003866: [patch] Sending Polarity/DTMF
Caller ID in chan_zap.
I have tried to apply the patch + polarity switch to Asterisk 1.2.0 and I end up
with some problems....
First I get a deadlock message when I try to send DTMF tones with:
ioctl(p->subs[SUB_REAL].zfd, ZT_DIAL, &p->dop) within the function
zt_call() in chan_zap.c.
? What is the best approach sending DTMF tones on the line still on_hook? Write
a new send_dtmf function in chan_zap.c file or somehow use ioctl with some
additional parameter etc...?
Is it possible to reopen issue 0003866 for a while, where we could try to
exchange knowledge to finally solve this problem?

Thanks.

Best Ragrds
