My sip provider does not require any user names and passwords.
They simple accept calls based on IP Address.
How do u set up the sip trunk to Accept calls from my SIP provider based on IP address. My sip provider can send calls from 1 of 5 IP addresses.
I also need to send calls out the same trunk.
All calls incoming calls from this SIP provider are coming in on
Executing [6468620064@from-sip-external:2]
make a trunk like this:
type=friend
qualify=yes
nat=yes
insecure=very
host=xx.xx.xx.xx
dtmfmode=auto
dtmf=inband
disallow=all
context=from-pstn
allow=ulaw&gsm
make a inbound route for your DID.
That’s it.
by the way, you provide your pbx box fixed IP address to your provider. In that way, the calls will be automatically reach your pbx. Your trunk will recognize the calls and send to inbound route.
