Share SIP trunks

Is it possible for a FreePBX install to share inbound and outbound trunks on a different FreePBX system?

If it is possible, is there a tutorial on how to do this?

Can they do extension dialing across systems?

Are there caller ID problems?

Any other issues I would have to deal with?

Thanks!
Mark

You want to set up a peer trunk between you two systems, it’s all in the wiki:
