Hi.
I have a very simple setup. FreePBX is installed on a VPS outside of my LAN. I have a CallCentric account linked to it. When you dial my callcentric phone number, it connects to an IVR, which announces a message, and then times out instantly and calls my phone (Cisco CP3911). If I don’t pick up it goes to my voicemail.
When I first set up my phone everything worked great. And then an hour or so later, all calls went to voicemail. I later discovered that the phone will accept incoming calls for about 1 hour, and then after then, it won’t accept incoming calls anymore. I can still make outgoing calls.
I’m sure this is something simple that I’m missing. (keepalives maybe?). I’m kind of a SIP n00b. I run a small computer repair business (very small, it’s just me) and wanted an IP phone instead of regular phone, so that I can have an IVR for a cool intro, and for when I grow and have more staff.
Thank you very much,
Zack Magee
