    From your log snippet:
    -- Got SIP response 503 "Service Unavailable" back from
    It looks like Asterisk is successfully passing the call to your gateway, but your gateway is giving an error. How many calls are being sent over the gateway when this happens?

    It could be that you already have 8 call going over the gateway and there isn't another port to dial out on. That, or the gateway is configured such that it does not automatically pass the call on to the next port.

    I have no direct experience with this gateway, but my guess is that you need to configure 8 trunks, one for each of the 8 ports on the gateway. Then set up an outbound route that has all eight trunks defined in it, and asterisk will try each one until it finds one that is not busy.

    Just a guess.
