I have no idea why this is happening, but I'm using FreePBX and i've setup Sangoma talk. It works perfectly fine over WiFi and 4G for some providers (Optus) but when i try to register the phone on 4G on another provider (Telstra), it can't authenticate. It only doesn't work on that network (Telstra). From my understanding of SIP registration, it should go like: CLIENT to SERVER: REGISTER SERVER to CLIENT: 401 Unauthorized CLIENT to SERVER: REGISTER (containing authentication information) SERVER to CLIENT: 200 OK I've setup a wireshark capture on my phone connecting from my Optus SIM and it authenticates without issue. I see in the SIP packet the Authorization, the digest username, the realm, the nonce and URI in the actual packet itself, it looks like the above. However when i look at the Telstra packet, the authorization part of the packet just isn't there? It's as if it never responds with the Authentication, which is strange, it looks like: CLIENT to SERVER: REGISTER SERVER to CLIENT: 401 Unauthorized CLIENT to SERVER: REGISTER CLIENT to SERVER: REGISTER SERVER to CLIENT: 401 Unauthorized CLIENT to SERVER: REGISTER CLIENT to SERVER: REGISTER SERVER to CLIENT: 401 Unauthorized (and continues) Does anyone know where i should go for this? Why would my phone behave differently on the 2 networks?

QNAP NAS Data Recovery

So i have a QNAP TS-453Be NAS which is running a RAID 5 configuration - 4 1TB disks with 3TB in total. It looks like the Data has been deleted (but not overwritten) and all the data doesn't seem to be there in the file epxlorer. I want to run a dd image backup across the logical volume - is that possible for a RAIDed QNAP NAS? Or can i just DD each drive and somehow glue them together with some fancy software? Otherwise is there any native QNAP apps for something like this? Can anyone point me in the correct direction? Any shred of information or experience would be greatly appreciated.
