Has anyone setup a sip trunk to Twilio?

[ncmurf00]

this should be pretty but I can't seem to get a link.

have the user and password set and the ip security verified.

anyone successful in getting online with them?

Jeff, I haven't personally heard of anyone working with that particular provider, but that doesn't mean someone hasn't done it. Are you having issues getting the trunk registered or making calls? Thanks

I'm trying to do this as well, but their documentation doesn't really help.

Did you end up getting this working?

Hey Nick,

I did... it took a lot of trial and error.

Are you doing one or multiple trunks to the Adtran?

Thanks,

Jeff

That's great new, Jeff!

I'll be doing multiple providers, but only one of which would be Twilio (to start at least)

Would you mind sharing your config on how you got it working?

Thanks!

I did this recently with a trial account. I only configured for outbound LD unencrypted, so there may be more to your config. The trial account only allows calls to and from verified numbers and both dnis and ani must be in E.164 format.  Also they don't register the trunk.  You create a custom URI to connect to  custom.pstn.twilio.com and a credential.

Here's how I converted 10 digits to E.164

match dnis "$" substitute "0111$"

match ani "$" substitute "0111$"

voice international-prefix abbreviated

sip grammar from user international

voice trunk T0X type sip

  match dnis "$" substitute "0111$"

  match ani "$" substitute "0111$"

  sip-server primary custom.pstn.twilio.com

  outbound-proxy primary custom.pstn.twilio.com

  domain "unisip.pstn.twilio.com"

  codec-list TRUNK both

  authentication username "custom" password encrypted 12345

I also have the TLS sip trunk for Twilio functional.  I created a ca profile and imported the thawte Premium Server CA. Twilio says you need all the Thawte and Digicert CAs, but I had trouble when I added more than a few certs.
