Hi guys,

I was trying to change my music on SpeakMediaPro from my cordless phone via my Pc's skypeIn number and to my surprise  SpeakMediaASR didn't respond to the DTMF as there wasn't any coming through from pstn. Just a short chirp and then silence like it was being filtered and I'm not kidding it appears to be exactly that, it wouldn't be hard to do and it wouldn't really have much effect on speech unless of course you happend to talk like microsoft sam.

It could just be a glitch in the system or it could be due to a certain telco thats taken it upon themselves to thwart a 3rd party who intends to utilize SkypeIn numbers to route calls internationally.  A few months ago there was some report about a company buying up a lot of skypeIn numbers here in NZ and I can only think of one reason you'd do that and Skype offers a really low cost solution to go from pstn to voip.

I'd be happy to be told I'm wrong, I just want the DTMF back so I don't have to go upstairs to change the music!

(SpeakMediaPro the voice activated media player, the beta version utilizes skypeIn so you could control the player remotely from where ever you are via a mobile phone or landline)

I wouldn't think there's a third party filtering DTMF based on destination number... It could be some interference created by latency for example?

The quality of Skype calls using SkypeIN numbers in NZ is very poor. I suspect it's a case of the PC not being able to detect the tones due to the compression that is occuring.

Yes I thought of that but I'm not so sure the jitter in skype was fine. It only came to me attention a couple of days ago, I thought I'd broken something but then I had a few of my users call me telling me it wasn't working for them and after doing some tests it really did look like it was being filtered. 

Pressing and holding down a key results in a short chirp then a very silent tone thats almost inaudible.

I spent a whole day testing it and also tested another skype guys software on two Pc's and still same result no DTMF coming through
its not really a big deal but it does kind of dent my application of it here at least.

How the heck am I going to control SpeakMediaPros stream to my cell phone if I can't dial home and change the music!
I don't want to go back to my mp3 player. With 3gb of data on vodaphone and the abilty to stream my music from home, I don't have to sync or copy any media , I just phone home and say it to play it.

I hope you're right anyway there have been a few issues with SkypeIn but I hope the DTMF issue is only a glitch.

Perhaps not but it would be a good story unamed telco thwarts cheap toll call service.
