Okay, here's a wierd one for you. Or, maybe it's just really simple and so am I.
I'm trying to enable 911, and other X11 service number access on our Asterisk system. We're using all SPA50XG phones with a few SPA942's thrown in here and there. I have the Asterisk side worked out. I tested it from an analog extension on an FXS port and all works as planned. But I can't seem to get the right dialplan configuration on the SPA50XG's.
Here's the Extension 1 dialplan from the SPA509G I'm testing with:
Everything but x11 works. If for example I dial 9,811, the phone comes back with "Incomplete Address" in the display and a reorder tone. I'm watching the Asterisk log as I dial and the dial string never makes it to the switch, it's erroring out at the phone.
I'll read through the manual tonight, but I was hoping someone else had run into this and might be able to tell me what I'm doing that's making my phones so unhappy with me.
