Another EBay hobby aquisition.
I have enjoyed learning a reasonable ammount about IP telephony through the purchase of some cheap Cisco 7940 and 7960 IP phones on Ebay.
To the extent where I had built a small Asterisk (open source PBX) based exchange in the house with several of these phones dotted about the place.
A source of constant frustration to my wife and amusement for my work colleagues when I tell them my wife was getting fed up of dialling 9 for an outside line just so I could experiment with dial plans.
Anyway, I have offloaded a few of the older model 40′s and 60′s and bought one of these colour touch screen 7970G’s.
Blimey – they are much harder to configure than previous versions. It doesn’t help that Cisco like to keep the configuration data file formats to themselves. As you are supposed to deploy and configure these phones using their VERY expensive unified communications software suite.
I am endeavouring to configure the SIP based settings to work with my Sipgate Internet telephony service subscription. This is something that was reasonably easy to do with previous Cisco phones.
If anyone has managed to get the 7970 working with sipgate behind a NAT firewall/router I’d be very glad to hear from them.
