[asterisk-users] Issue with trying to dial two different servers at the same time.

[Steve Anness]

Okay, so my issue isn't really a technical one but more of needing
advice on the best way to program this.  I have a user in Colorado who
works from home but frequents our office in Colorado.  All of our
remote users connect to a server in Dallas the users at the HQ in
Colorado connect to a separate server in the Colorado office that is
on the private network.  I have an IAX trunk between the two servers.
I also have an IAX trunk from my local server here in Texas.  I am
using this dial command to try to ring both phones at the same time:

exten => 12109,1,Dial(iax2/castle-rock/109&iax2/colo/17128,20)

This has one flaw, if for whatever reason his home phone isn't
connected, like it isn't now, than when I call 12109 I get his home
voicemail as it picks up right away.

How can I program this so that even if the voicemail on 17128 or 109
pick up it still rings the other phone?

Thank you all for your advice.
