SBC on Debian 8 - How to delay service start?

[AndyC3PO]

Hi Guys,

We're running SBC on Debian 8 with a hosted Google Cloud 3CX environment. We are having an issue with phones taking a significantly long time to register with the 3CX after rebooting the SBC. This issue is worked around by restarting the SBC service on the SBC device, but obviously, this is not a solution.

We have previously experienced the same issue with a Raspberry Pi, and were able to resolve it by delaying the service from starting up at network. This was easy to accomplish by using the raspbian config tool. Not being Linux gurus I'm hoping there's some other people out there who have experienced this issue and resolved it, and which config files to modify and how?
