A client of mine has switched to RingCentral from another VOIP provider. They are using SNOM phones (model 710 I think, but not positive).
I was asked to open a list of ports on their router, and once that was done they ran some off-site tests and concluded the router was set up correctly.
The problem is that the phones can make outgoing calls but incoming calls do not reach them. The provider is claiming that the SNOM phones must be "locked", (like a cell phone with another provider) and that they are going to need to contact the old VOIP provider and see about getting the phones unlocked, or else replace the phones.
I don't know enough about VOIP to know if my client is getting a good answer from the local rep for RingCentral.
What do you think?
