I have an asterisk home PBX and I recently got a Cisco 7960G on eBay. So far I got everything working but the background images are quite tricky. I followed one short how-to and I was able to actually upload an image onto the phone. But when I tried making my own image, it just fails weirdly. Left to right, the image starts to display in about 1/3 of the original image and it is then wrapped around so the first 1/3 of the image is on the far right. I checked that my image is 90x56 greyscale bmp just as the example given on that website. The example image works fine. Can someone please tell me what it is I'm doing wrong?
I am serving the image from nginx over http (not https), the line in SIPDefault.cnf is:
(breaking the link up with spaces so that stackexchange doesn't think this is a link. I don't have enough rep to post that many links, apparently.
logo_url: "http:// my_server_hostname/ sip/ homer.bmp"
This does not work at all:
How it looks on my phone:
