Nortel 1535 & Android Video Conference - SUCCESS
We identified an Android H263 client for 2way video conferencing with the Nortel 1535.
We have 2 Nortel 1535's registered as extensions on our Asterisk box. One of them is physically located 1000 miles away.
I played with several VOIP clients on my android phone but most had proprietary video codecs. I found one that has H263 as one of it's codecs. The Client is advertised for developers.
I installed IMSDroid 1.2.355 from doubango.
Here is what we did to video conference between my cell phone and our Nortel 1535.
Example assumes 205=the extension your Android SIP client will register to. Also assumed myasteriskbox=asterisk IP or URL

We did not have to use NATT for a successful video call.
Dial the extension of your Nortel 1535 using the Video call option (If you call using the voice option you will not be able to convert the call to a video call). Have your partner answer the call using the Video button on the Nortel. Video will begin to show on your Android.
The Android does not send video automatically. Click on command then click on send video. Once send video is clicked, click command and click Switch Camera.
The moment you click Send video, the Nortel will begin receiving video. Depending on your cell phone you may not have a front facing video camera. Our Samsung Galaxy S is one without a front facing camera. We click Switch camera, so the cell phone can switched to the back facing camera and begin sending what it see's to the Nortel 1535.
Pro's: Video Conferencing works on your cell phone
Con's: Depending on your bandwigth audio suffers. Even using the lighter audio codecs audio suffered. Also if you do not have a front facing camera the recipient of your call is seeing whats in front of you and not looking at you.
Summary: We find it convenient to be able to provide coverage of live events to our partners. Videoconferencing with my brother on my cell phone while walking through South Beach in Miami is a thrill for him. This is an interesting platform worthy of further exploration.
