Hi all, First I need to tell you that I have almost zero experience with SIP servers. I am familiar with VoiP networks, DHCP options, and the like, but after they are on the network and functional I am not longer involved. Until the following situation came up, that is… I figure I need to dive into this as some point so may as well be now! On an aside - please feel free to share any resources that would help me get my head wrapped around SIP servers and VoIP technology.
Project advice sought - I need find/program a sip server (I think) for an installation that had one running on a RPi. Somebody removed it and the system stopped working - imagine that. They are asking me as the IT guy (me) to fix it… These are GS phones (5 or 6) with large display and are about 3 years old… (edit: the phone model is GXV-3275) running Android? There is no phone service per say - this was setup to answer calls strictly from 2 Axis outdoor door stations with IP cameras - video door that would ring the phones inside when somebody pushed the button.
I am good with Raspberry Pis, and the networking part of this. Any advice on how to get his back up and running. Should I figure out Freepbx and figure out how to program it? I only know the name perhaps there are better solutions. Any other way I should do this?
Thanks in advance for any/all help and sorry for the long post!
