SPA2102 Setup Guide

Credits to Val, thank you for your help.

The attached PDF will help you set up your SPA2102 device from scratch. It is a known working configuration so if you are having troubles with your SPA2102 reset back to defaults and follow this guide.





Edit:
1) Navigate to Voice-->SIP-->SIP Timer Values (sec)
a. Reg Retry Intvl should be changed to 120 seconds
https://support.freephoneline.ca/hc/en- ... redentials
("Failed Registration Re-Try Interval: 120 seconds")


b.Mango suggests the SIP T1 default setting is too aggressive, and to help resolve potential registration issues, T1 should be set to 1.
Navigate to Voice-->SIP-->SIP Timer Values-->SIP T1
Change SIP T1 to 1


2) In your SPA2102, Navigate to the SIP tab-->NAT Support Parameters, and make sure that the following settings are enabled:

a)Handle VIA received-->yes
b)Handle VIA rport-->yes
c)Substitute VIA Addr-->yes

3. In your SPA2102, Navigate to Line 1 (or whatever you're using for FPL)-->SIP settings, and change SIP Port to a random number between 30000 and 60000. Do this for security reasons (to help avoid SIP Scanners/hackers). Also, this step may help to temporarily address a corrupted NAT association that's developed between a router and ATA (if you're having registration issues, try selecting a new random port number in this range, and then reboot the ATA. If that works, you were dealing with a corrupted/stale NAT association in your router).

4. In your ATA, navigate to Voice-->Line (whichever you use for FPL)-->Supplementary Service Subscription-->Block CID Serv:
a) change to no
b) Click "submit"
Do this to avoid 15 minute call disconnections.
