It has been working fine for months. The only thing I changed yesterday was the CID on the outbound but put it back after it made no difference.

Now they are getting all circuits busy from all extensions on outbound calls. Inbound calls are fine. This is driving me nuts.

Still getting the error message... It makes no sense.

Outbound CID is specified with the 10 digit number <aaabbbcccc>. I changed the numbers to 6[012] and am trying a call now....

I am having difficulty implementing this and not sure why. I have 3 extensions that I want to use the alternate trunk. In the outbound routes, I put 6x in the caller id field as shown in the examples. The three extensions are 60, 61, and 62. When I try to make an outbound call, I get an "all circuits busy" message. Inbound calls flow to the correct ring group. What am I missing?

I am running Nethserver for a local email server for internal-only messages. Curious to know if anyone else uses it.

@ccwtech Once I get everything fine-tuned I will be making test calls to the PSAP to ensure everything is correct since I just added the new trunk and DIDs last night.

I set up separate e911 addresses in the portal as well. The system covers 3 buildings on 1 city block. I know they are not set up geographically different as yours are but wanted to make sure each group goes out the appropriate trunk - hence the reason for my question. Your examples are very informative.

Yes. It makes sense now. I was trying to make it more difficult. Your examples make it all clear. Thank you.

@jaredbusch That makes sense now. What was confusing me was the 11xx in the first image. Your example does not include the xx. I will try this afternoon and see what happens.

The extensions are not in a group.

I could be reading into this wrong.... Do I need to prepend the dialed number with a number to force the calls out a specific trunk?

@jaredbusch Ok. I have to figure out where to insert the extensions for the route.

@Dashrender Lets say my extensions that will use the special route are 60 through 65 - would my dial pattern start with the extension number? That is what I'm guessing by the image you posted above. I do not use codes to grab an "outside line" like dialing 9 then the number. They have however learned to follow the number with # so the call goes out faster.

@jaredbusch Now I just have to sit down and figure out how to set it up so that it works correctly. So far, they love everything about the system compared to what they had before. The best is how much the phone bills went down. I still have a couple numbers to port over.

@dashrender This might be the easiest. They only have 2-digit extensions. of the 30 extensions, only 4 or 5 would need alternate routes. I'm still pondering this method.
