Callout GoIP with Elastix

Hi all,
How can I configure goip and elastix to dial an external number (cell phone)?
thanks and regards

By contacting their support teams or using their peer support forums!

I’m surprised they need special treatment for this.

Thank you @david551
P.S. : I am a beginner in this field, and I did not find a good tuto to start

For bare Asterisk you could try starting here: http://asteriskdocs.org/en/3rd_Edition/asterisk-book-html-chunk/asterisk-OutsideConn.html

However, to be useful, I imagine you have already done some of this and we do not know heat obstacles Elastix and GoIP put in you way.
