Friends,

I just wanted to drop a note about my adventures yesterday.

I spent the whole day working with a company that works with telephony for the deaf. We worked on a couple of issues, one that was very interesting.

They're using videocaps, a branch based on trunk. They have SIP phones and set up calls and Asterisk chokes and denies the calls - so they called me and asked me to explore why?

I looked at the dialogs and discovered an INVITE

SIP headers looked fine.

SDP looked fine.

But wait! There's a media session for video. And there's a media session for text in the SDP.

Aha! No audio!

- "Who need's audio?" they said (through a sign-language translator) and looked at me.

So we debugged and debugged and finally got calls to go through, but at that point one of their clients crashed and we decided that it was too late to continue this experiment. I think we almost got there and got Asterisk to accept that "phone calls" doesn't have to include audio.

You live and learn. And with this message, I'm disappearing into the Swedish midnight sun to celebrate midsummer here in Sweden. It's the height of the year and as close as we get to a national celebration. Everyone burns meat to coal, drinks akvavit, dances around (with or without clothes) and ...just enjoys the sunshine, the nice weather (disregarding the fact that it has been raining on many midsummer nights in the past, but who care's...)

So if you see any commits from me during friday, please revert them and ignore them :-)

Why not use the sound channel to encode vibration then?
