HT802 can't place outgoing calls - fast busy every time
Posted: 08/04/2020
I know that this topic has had some coverage here on the forums and I've scoured them for ideas, but so far no luck.
I've been using FPL for over 10 years using a Cisco SPA112 with almost no issues. This week I'm trying to help a friend to "cut the cord" and I've been trying to set him up on FPL with a Grandstream HT802 box. I followed the configuration options outlined in this forum here: http://forum.fongo.com/viewtopic.php?f= ... 839#p74000. In brief, I'm using "Keep Alive" NAT traversal and random ports and the dial string recommended by FPL (changing the braces to {} from ()).
Unfortunately I can only receive calls with the device. Every outgoing call goes to a "fast busy" signal.
I've tried playing with the Dial Plan settings and even placed the HT802 in DMZ on my router. I also tried a STUN server.
My router is an ASUS running Merlin so I was able to also configure the UDP unreplied timeout settings recommended in the forum, but still no luck. No problem registering on FPL, I just can't place calls.
When I reconnect my Cisco SPA112 I have no issues (other than a long-standing issue where I'm forced to change my Primary SIP Server to voip2.freephoneline.ca after a power failure or the unit never recovers by itself, suggesting some kind of NAT issue, but that's perhaps another topic).
The odd thing is that the Status page on the HT802 is saying "Unknow NAT". I also don't see anything in the status page for provisioning (it says it will download some XML file).
I'm also wondering if FPL keeps track of a MAC address and won't let me use a different device for my account?
This is not going to become my device, but I would like to ensure that it works for my friend before installing it at his home. Any help would be appreciated.
