Not the best, not the worst, but the generous credit lets you tinker for quite a while. Pure outbound termination comprises 2 charges (all in USD): $0.0065 ("relay call" - the external transport?) plus $0.0007 ("relay SIP call" the internal processing?) rounded up to a minute so you pay $0.0072/minute with minute rounding. I've been using it for a year now (tip 'O the hat to user - I think he was the one who clued me (all of us?) in initially.
It is not trivial to set up but once working seems to chug along. To my way of thinking Signal Wire is a great addition to one's quiver of VoIP providers. (In that respect I am already a bit disappointed).
Practically, it doesn't hurt to have one more alternate outgoing trunk, especially if I can get good quality international calling, but that is left to be seen as the international call activation is a complicated thing which requires verification (of what I am not sure yet), approval by a their higher-up etc. My real interest in Signalwire is to do some digging into their integration capabilities/solutions with freeswitch, so from that venue the bonus starter was great. But 3/4 of a penny per minute rounded to 1 mn is still in the same league as callwithus which charges 0.9 cent/mn with 1mn rounding. As I said in my post they charge you for everything even for calls that didn't go through and they are not particularly competitive. You will use both pieces in your registration string and peer settings with chan_sip.Īs for the pennies for the verification calls, you're right. When you create the SIP endpoint on Signalwire make sure that in addition to the user name you create a password (right below the username box).
I did not white list any of their numbers. : I used a chan_sip trunk per ward's post further up in this thread, with a small change I did not use a /DID at the end of the registration string as there will be no incoming calls.
