I have a customer with 2 SPA942's connected to a Sipxecs IP PBX. CTI is enabled on both phones, still the configured Line Key remains Solid Amber.
I was able to find a thread showing that this is an issue with that specific PBX and the SPA942. However, I was wondering whether there is a special syntax for the extended function within the SPA942. Also, what server type could the Sipxecs be - Broadsoft, Asterix or else?
Thanks for any feedback!
