I found out from tech support that the nokia gateway’s do have the ports permanently blocked. They are sending me another model (not sure which one yet) that is supposed to have the ports open.
We are experiencing something similar with dialpad.com. I’m wondering if T-Mobile is blocking ports intentionally so that one can’t use another phone company. Sounds fishy…. These are the ports we need to have open.Port and protocols used by Dialpad phones and applications residing in a private network are listed below. Outbound port configurations are needed on the firewall to allow traffic to the destination ports listed in the right-hand side column of the tables. Stateful firewalls are recommended for Dialpad deployments. For a stateful firewall, inbound port configurations are not needed as they are automatically opened as a reply to the outbound traffic.
