Newbie - Would like to link 2 Asterisk servers together!

Very new to this. I’ve currently got two Asterisk servers in two different locations, but visable to each other across a Wide Area Network.

I have some software IAX phones hanging off each end for testing which can dial each other locally. I would like to be able route calls between the two PBX using VOIP, but don’t really have a clue where to start.

Any ideas ? :open_mouth:
