The Number you have Dialed is not in service

Inbound & outbound calls are just saying Number you have Dialed is not in service… Not sure what I’m doing wrong.

I have a Grandstream GXW-4108 FXO Gateway with 8 pstn lines coming in. I ran the Grandstream Line Analysis and it looks like all of them are getting a decent signal.

I followed the instructions on this guide:
http://www.freepbx.org/forum/freepbx/tips-and-tricks/how-to-grandstream-gxw-4104-setup
All of my settings match up.

Any ideas what could be causing this? I’m pretty sure it’s a setting in the PBX Since the signal is getting to the gateway alright, and the gateway SIP is registering correctly

qualify=yes
secret=shadow4t4

Inbound Route:

rest is default

Outbound Route:

Local 7/10 Dial Plan

Trunk Sequence
0: 7344254403

How is host=dynamic going to work?

What should it be set to? The IP of the phone to ring?

Have you spent some time on the wiki yet? It’as all explained in there.
