I've just stumbled across this forum whilst I was doing a little late night research about the Cisco 7970G model. Has anyone within this community ever managed to successfully connect this model of phone to a Hosted PBX provider? After purchasing two of these phones recently, I updated the firmware from SCCP to SIP 9.x.
Although, after I pulled up the XML configuration for the phone, I've exhausted most ways of trying to get this phone to register with the remote based Hosted PBX provider that I am using. I have managed to get the Cisco 7960 and SPA models of Cisco working perfectly fine within the past. Although, the 7970 seems to be more troublesome and I have no idea what's preventing the phone from provisioning.
Is this particular phone more exclusive with the Cisco CallManager in oppose to being used alongside of remote hosted PBX providers?
Within the phone's config file, I have completed the configuration for the following settings:
Outbound Proxy Port
I am not using CallManager to manage this phone, so I can't really get a great understanding for what's going off here in terms of the phone's provisioning. I have read that this particular phone model does struggle to connect to a wide variety of UK based hosted PBX provider networks. Not sure whether this is true or not?
All the same, I hope someone could advise me on this a little (I'm in two minds whether to sell the phones on and go down either the Grandstream/Polycom Route instead)
Any advice would be most welcomed!
