I am trying to get a Grandstream GXW410X working with a hosted freepbx set up.
I tried to do a chan_sip trunk.
Here are my setttings
Trunk Name = Same as SIP user ID on the grandstream
secret=XXXX (same as secret on the grandstream_
host=XXXX The public ip of the grandstream. I did go ahead and forward ports 5160 to the grandstream IP
I had tried it without the port. I get an all circuits are busy.
Dial(“Local/8818482107702@from-internal-0000000b;2”, “SIP/700/18XXXXXXXX@GXW4104-1,300,T”) in new stack
