Asterisk-Friendly SIP Trunk Providers

Is there any list of providers that support Asterisk?
I’ve looked through several providers, both signed up & topped up their API with no luck on configuring Asterisk or a guide to use Asterisk with it.

If your provider is supporting SIP then should be no problem to connect with. I never met a SIP provider with I can’t connect using asterisk.

Which provider do you use if i may ask?

What compatibility problems have you encountered?

Asterisk speaks SIP and is compatible with the majority of SIP trunking
providers. Those that are not compatible are often found to have broken SIP
implementations.

I doubt that many providers even know whether they are compatible with
Asterisk or not - assuming they don’t use it themselves, they probably don’t
ask their customers what they’re using either.

I also think that if you’re looking for advice on finding a suitable provider,
you need at least to let us know which country you are looking for the service
in.

Thank you for the quick reply.

I have tried 3CX & AirCall, both which don’t work in my case.
I need international calling.
It was a pain to try to setup 3CX, therefore. And I didn’t find any guides for it either.

I don’t undertand. 3CX and AirCall are both software applications, not SIP
trunking providers.

As an aside, “don’t work” is not much information to go on for anyone trying
to help you.

I need international calling.

Yes, but which country do you want your own numbers to be in?

I’m sorry for explaining badly, I’m in the middle of something.

It doesn’t work, as in I can’t find a suitable provider which offers a easy setup-guide. I’m not much of a Linux person myself, and therefore a guide would atleast be helpfull.

If my number could be (+1 - US) that would be fine, but an provider with a dynamic callerid (changable) would work better in my case as we operate with several numbers.

Any SIP provider should tell you what you need to know (but it won’t be
specific to Asterisk). They will tell you:

  • the hostname or IP address you need to connect to
  • the username / password you need to present if they use this form of
    authentication
  • otherwise they will require a static IP address from you which is the
    address of your Asterisk server which will be connecting to them
  • they will also tell you the numbers you can be called on, which will
    automatically also be the Caller IDs you can present on outbound calls
  • which codecs they support / prefer

This information will allow you to set up a SIP connection in Asterisk. There
are many guides on the Internet telling you how to configure a SIP trunk in
Asterisk.

If it’s technically too challenging for you, I suggest you try FreePBX, which
is based on Asterisk but provides a front-end GUI for configuring and managing
it. FreePBX is perfectly capable of talking to trunking providers. Note that
although it is based on Asterisk, it does have its own quite spearate support
community and forum, so if you choose to use it, your questions would better
be directed there.

If my number could be (+1 - US) that would be fine, but an provider with a
dynamic callerid (changable) would work better in my case as we operate
with several numbers.

So, are you looking for a provider who will allow you to place outbound calls
carrying a Caller ID which is different from any inbound number you have with
that provider?

That is an uncommon thing for providers to permit, because it enables people
to spoof the Caller ID and pretend to be placing calls from other people’s
numbers.

What is your justification for needing to be able to do this?

I’m not saying it’s an impossible requirement, but it certainly cuts down the
number of providers who would be prepared to offer such a service. It’s also
something which is being more and more legally restricted in many countries.
