My bad, I searched for the freepbx dial pattern but it did not occur to me to look into voip.ms. I will try that.I don't have Voip.MS but looking at this wiki, it looks like they expect to something coming at them like: 011+40 and the number. I don't know if the plus sign is actually wanted. That assumes 40 is the Romania country code and the plus is included in the dial string to Voip.MS. Here is the link to the wiki: https://wiki.voip.ms/article/Dialing_Rules_and_Patterns
I'm not sure why your asterisk is not starting for you. I used ward's script to install it on my server at cac and did not have any issue. If you stiil have a problem, you might try using vitalpbx 2.3.8 with the incredible add-ons that ward fixed up, which is what I am currently doing.How did you install PBX 16-15.2 on a CloudAtCost server. The asterisk does not start for me. PBX 13-13 woking OK. However, in the last few days they have significantly improved the speed of 711/313 Mbit / s.
