Trixbox 2.4 incoming calls with Global Crossing sip

I set the trunk settings as follows...

[outbound]

host=IP.OF.GLOBAL.CROSSING
type=friend
insecure=very

[inbound]

host=IP.OF.GLOBAL.CROSSING
type=friend
insecure=very

with no luck.

Outbound works fine.
Inbound works IF anonymous is enabled.

I've also tried putting context=from-pstn and nat=yes (on GC's recommendation) in the inbound settings

they do not use authentication, rather they just allow my static IP to connect.

When i do a CLI> asterisk -rvvvvv I get the following messages in my console when I call that DID string:

-- Executing [INBOUNDDID@from-sip-external:1] NoOp("SIP/IP.OF.GLOBAL.CROSSING-b7808b70", "Received incoming SIP connection from unknown peer to INBOUNDDID") in new stack

The caller never receives a ringing sound. it just sits quietly until the error message plays.

NOTE: I currently have a working SIP trunk with another provider that works in/out no problem.

I'm completely stumped once again.

Any ideas are appreciated!

Thanks!

Thanks for your help Scott.

Here's what I figured out.

For some reason when trixbox would reload config. whatever was in sip_additional would be reset to the first setting i had:

[GlobalCrossing]
host=IPADDRESS
type=peer
insecure=port, invite

Which is wrong.

However when i would go into the command line editor, or NANO in the command terminal, I could paste these settings:

[GlobalCrossing]
host=IP.OF.GLOBAL.CROSSING
type=friend
context=from-pstn
insecure=very
disallow=all
allow=ulaw
nat=yes

Which work.

however, any time I reload config on Trixbox (changing an extension. or route, or anything) it resets the settings in sip_additional to the old setting again.

I may just write myself a note to remember i have to rebuild that peer setting every time.

thanks again!
