Howdy,
Having some issues connecting Digium phones remotely. I’ve opened up the ports in the firewall as per many articles (and then some), but the phone sees the server, then times out at the proxy when getting user lists. I had removed the phones from EndPoint Manager earlier to avoid some other issues internally, but will I need to use EPM instead of DPMA for phone configs for the remote phones? Both? Only EPM? Or am I barking up the wrong tree altogether?
I’m experiencing different levels of depth for different users, some only contact the proxy then timeout on downloading sip info, others can pull down the registration info but no ability to call out.
FYI we cannot set up a VPN for each remote phone. I’ve googled the crap out of this subject and have tried everything. Maybe y’all can help.
UPDATE: Brought home a polycom, plugged it in, put in username and password, connected without issues and is working fine. So, definitely a digium configuration issue.
