I am having problems receiving calls on my voip line from cell phones.
Asterisk tries to “DIAL” my ata, but I get this error:
[Mar 1 20:20:45] WARNING app_dial.c: Unable to create channel of type ‘SIP’ (cause 20 - Unknown)
or “Cause 406 - Not Acceptable”
---- after this “dial” failure, the cell phone is sent to my asterisk voicemail, which works fine.
I dont know why, but a friend of mine who used telus went from being unable to call me (cause 406 not acceptable) to being able to call me when he called telus to have his callerid made public. Might just be a coincidence.
Any idea? This is in Canada, and my asterisk 1.4.22 setup is running on an “unslung” NSLU2.
