Need help with Trunks

I have the following system up and working for the below:

  1. I have a FreePBX Server setup with SIP Trunking to a provider.
  2. I have a ShoreTel Phone System
  3. I have SIP Trunks setup between the ShoreTel and the FreePBX.

I can register a softphone with the FreePBX server and make calls to the VOIP Provider. I can also dial an extension from the softphone to the ShoreTel system and it works just fine. I Can dial from the ShoreTel system to the FreePBX system and it works just fine.

What is not working:

When I dial from the ShoreTel system to the VOIP provider, it makes it to FreePBX but I get an error back from the VOIP provider. See below. Here is what is happening and trying to figure out how to remove the /s.

Called voip/s

When a call is made from the Soft Phone to the FreePBX system and out to the VOIP Provider is works and this is what it displays:

Called voip/19999999999

It appears not to append the calling number when it is from the ShoreTel to the FreePBX to the VOIP provider?

Any help would be appreciated.
