Thanks for giving some meaningful feedback. It was very helpful. I was able to get my hands on an Aastra 6737i to test with. As you suggested, it worked fine. So, that leads to the fact that we know it doesn't work on many Yealink models as reported in this thread. Also, there are these reports:
I'm not sure which 3 endpoints @lgaetz was using, but the problem has been experienced on Yealink, Grandstream, Linksys/Cisco, and Siemens. On the other hand, Aastra devices work fine. Is it possible this is a problem that affects many brands and devices?
@tm100 - That is a little different, you previously insisted this should be reported to Digium/Asterisk. Were you able to identify the problem? I would be interested to know what led you this new conclusion.
