Hi there everyone! I'm trying to setup the 8865 multiplatform with a standard SIP provider (Telnyx, in this case). I think I bit off more than I can chew. I've managed to get the phone to register briefly, but then it'll lose registration. All Telnyx is providing is what's available at sip.telnyx.com. I'm utterly frustrated. I get a dialtone but can't dial out (silence once I dial), and Telnyx is telling me none of my inbound calls are being received at the 8865. Please help!
