I have a SPA9000, SPA 400 configured with 4 handsets and sip account. The software version of the SPA9000 is 6.1.5 and of the SPA400. The firmware version of the SPA 400 is 188.8.131.52
I'm very happy with call quality etc having spent some time tweaking the settings. The problem I'm having is caller ID. Having received various settings from the reseller, the caller ID now works occasionally - approximately about 1 in 7 times.
Does anyone have any suggestions on how to improve this further. I located in Ireland
