This is what the Folks on the other side are seeing:

The NLCR and LCR is what i mean by similar to SPNET. But if you don't need to dial the extension directly from a handset you don't need to worry about it, as mobex has a TG and outgoing digits fields so you can put 805 12345#

Your issue with the sip it the proxy domain name field.

Ask them what their realm is, then set that as the proxy domain name in the sip settings

They managed to get it to work with settings on their end without me changing the domain. The outside destination has an auto attendant, so I set a station group that overflows to another station group with a virtual SLT that is mobex paired to the sip trunk destination. That seems to do the trick.

I think we have it sorted.

Ok, next challenge with this on if you are still up for helping.

They have a second system connected through SPNet to the main system where the sip trunks are configured. Is there a way I can use the sip trunk on the other system? I tried allowing them to just dial the virtual, but it didn't do the external forward. I also tried to set up tandem trunking but that didn't work either.

Any suggestions?

Setup the sip trunk extension number that's being dialled from the main site just like you would a standard extension via SPNET.

Basically you're doing call hop off to the sip trunks.

A user on site 2 dials the sip number, call goes to site 1 via spnet, then out from site 1 via sip.

So let me see if I'm following, We want be able to have the remote site dial through to 85015520 where 8501 is the dedicated sip trunk and 5520 is the number to be called on that line.
sip trunk is on node 1
So, on node 2 I set 85 in the NLCR, translate that to 00185 with a wait length of 8 (8501 +5520) max digit 11 (node001 + trunk8501 + extension5220
then set routing digits 00185 with length 11 and route it through the SPNet LCR table

Does that seem right?

Not quite.

The remote site dials 5520, so set that up in the NLCR like you would for any other extension.

The main site will need the required entries in the DID table as per normal SPNET, the main site will handle the "hop off" from the SPNET trunks to the SIP trunks via it's LCR routing.

This assumes you've setup 5520 like a SPNET extension on the main site using NLCR but then sending via SIP not SPNET.

If you send me DB's I can tell you what to program where

Thanks for the Help Nameless. This one is on the back burner for a bit.

Cheers,
