I am not sure if this is in the correct area of this forum as I do not know if it is a dial plan issue or not.
I have a client that is having an issue dialing toll free numbers.
I have contacted the ITSP and they have assured me that they are not blocking toll free numbers so I am assuming that it is the PBX. Anytime they try to make an outbound call to a toll free number we get "we're sorry, your call cannot be completed at this time. Please hang up and try your call again later. Thank you"
The number looks like 1-866-xxx-xxxx
Has anyone ever encountered this problem before?
Thank you everyone for your help!
