Dont know if you were seeing my old posts, but I used to have them as a provider and was never able to get outbound to work. I was convinced it was a dialplan issue, but support was not familiar with the device, and they could not help. I even sent them a unit and they kept it for a month. I gave up on them and got the unit back. I was moving to my own FreePBX system anyway so I just gave up on the issue. I think it was dialplan related myself. Inbound worked. I even tried using some Cisco ATA dialplans that virtualpbx had supplied. I just went to their site and looked for new ATA documentation and there is nothing new. Looks like they revamped their site, but no new content. I was a 7 year customer. I dont want to slam anyone personally, but when some were promotoed and moved out of support their level of support tanked. I could not even explain to some of the support personnel what an ATA was... Sorry I cant lend anything more substantive but I spent probably 100 hours trying to get that unit to work for outbound. I wanted to deploy it for all of my remote workers and the obi portal was exactly what I needed to manage them. Now that I am using FreePBX, zero issues. Feel free to PM me if you need any more info.
