I have several 7940s set up and running fine with 3CX, the only remaining issue is to do with integrating with the company phonebook. The phone is only able to display the first 32 entries of the phonebook, pressing the 'next' softkey briefly displays 'contacting http server' but then nothing happens. I understand that this is a feature implemented by cisco to reduce network load and that additional coding is required to allow the 'next' key to function properly. However I have no idea how to proceed. If someone could point me in the right direction of where the coding changes should be made it would be greatly appreciated!!
