birefringence, it is your software, but I would be a big user of it were it able to reliably connect a call.
It is lazyness on my own part to want to fire a DTMF rather than key the number, especially long easy to futz international dialing codes, but I have to use land line phones and sometimes also radio autopatches. I was excited when I first got my (still everyday phone) N900 to see and try this plugin. I was also disappointed that it rarely worked for me considering the potential utility.
