Polycom HDX 8000 Interop with Sonus Networks NBS9000
Has anyone tried a SIP trunk from the Polycom HDX 8000 to a Sonus NBS9000 as the gateway? I am not seeing any messaging from the Polycom on the NBS. Pings are fine and IP polycom to polycom works ok. So the connection seems ok. Is there a SIP configuration that works best on the Polycom for this?
Doing pretty much standard TCP SIP port 5060. Thanks for any help.
