Ok, here is an odd one. In a second site (in which we have a pretty big language barrier with the local carrier) we've just received additional LS trunks. We've put them on the 6 LS ports on our controller. Now, we've gone over our ARS routes again and again, but once we dump then into a Trunk Group, we end up with failed calls. We put them on a set with a DTS button, and each one of those trunks are able to get out and dial.

We put them in a trunk group, remembering to both remove them from the DTS keys and reassigning them in the Trunk Service Assignment to ensure they are not DTS, check the route (9+7 digits) out to that trunk and it does not work.

Now, one difference is that before this, we had one working LS trunk on the ASU that we had set up the same and it worked fine. The difference now is that we are the Hybrid ONS/LS ports on the controller. It looks like a CO Circuit descriptor issue, but I honestly am not seeing it. Any ideas? Thanks.
 
What about using the Individual Trunk Access FAC and seeing if the controller can sieze it that way? Are you sure they gave you LS trunks, do you pull DT witha butt set?
 
Usually with LS trunks you need to set up a tone control plan to wait 1 second before dialing digits. Is it set up to do this?
 
No I haven't. Wouldn't I set that up in my ARS route? Thanks.
 
The tone control plan is called during Modify Digits. In the insert digits you need <TXX> where XX = the tone control plan.

The tone control plan is set up to dial DTMF after wait 1 second
 
kwbmitel is right. I can rarely use a LS trunk without the 1 sec pause as the local exchange needs to be given some time to "react" to the closed circuit and provide dial tone (voltage)
 
I've added that in, and unfortunately, our second site is in Costa Rica, and I don't have anyone readily available on site to use a buttset.

Now, when I call from our primary facility, over the IP trunks, I have an extension CFWA to an outside cellphone for the site director. I can call that extension, the system forwards me out that ARS route, and I can speak to him. But, users dialing from their sets can still not dial out. And we are both accessing the same LS trunk group. That one I can't figure out.
 
I would start looking at your COS and COR options for the trunks and stations.

If you have IP trunking between the sites I would also recommend you Statically assign a phone from your site to get it's call control from the Costa Rica site. This will allow you to test the calls yourselve from wherever you are.
