More on the Nortel 1535

Got PIAF purple installed and patched over the weekend. Setting up two of the 1535s to register and do video calling was pretty trivial. There’s a little bit of lag in the video but it’s not too bad. I also called the test numbers and there was no problem with the audio quality. Nice and sharp without drops, latency or jitter. This is running in VirtualBox with the extensions installed on a Pentium dual core. I’ve assigned 1gb of ram to the VM.

To turn on the video capability you have to add the following to sip_extensions_custom in the asterisk directory:

videosupport=true
allow=h264
allow=h263

Don’t forget to reload the configs!

Next up is getting Google Voice to work.

PIAF, VirtualBox and the Nortel 1535 phone

Wow, it’s been a while. I scored some of the Nortel IP 1535’s thanks to NerdVittles and this gives me a good opportunity to try to upgrade my Asterisk system to the latest and greatest version. Naturally I want to go with PIAF and they just patched to Asterisk 1.8. I’ve considered using the Incredible PBX build but I don’t think I need all that stuff so I’m going to try straight PIAF first and see if I can get the Google Voice parts working at least.

First up, I’ve installed it in VirtualBox. Now, I’m concerned that there might be a stuttering problem because it’s virtualized. No way to know until I get a phone online. I’m hoping this will help but I installed the VB additions. It was relatively painless following the steps at if (!1) 0 with the exception of changing the kernel version to match. Rebooted and it looks ok so far.

More to come as I get phones online.
