I have couple of phone numbers with Flynumber that are forwarded to my own SIP server.
I can successfully receive calls, but I’d like to know how can I make outgoing calls.
Is there any outbound proxy I can use for outgoing calls?
You’d need to use our SIP accounts, check out this post for more info
Alternatively you can contact your own SIP provider to enable outbound calls but that wouldn’t have anything to do with us
