For what it's worth, Acrobits Groundwire doesn't require a subscription fee for push notifications using Freephoneline (by itself).
1. In the Groundwire app, Under "Account"
a) Username is FPL SIP Username.
b) Password is FPL SIP Password.
c) Use voip4.freephoneline.ca:6060 for domain. voip4.freephoneline.ca:6060 helps to circumvent potential SIP ALG issues in routers.
2. In the Groundwire app, navigate to advanced settings for your FPL account.
a) NAT Traversal should be set to Auto and keepalive period should be set to 20s
b) Set Proxy to voip4.freephoneline.ca:6060 (proxy setting appears to override whatever is entered for domain by the way)
c) Set Expires to 3600 seconds
d) G.711u-law should be the highest enabled codec, and packet time should be 20ms. FPL only supports G.711u and G.729a.
e) "Outgoing calls need registration" needs to be enabled due to the 15 minute session timer that Freephoneline uses. If "Outgoing calls need registration" is disabled calls may drop after 15 minutes, particularly when using cellular data (the only way around not having the setting enabled is to place the call on hold and resume it before the 15 minute mark is reached).
f) Set a display name using your name, and don't use "anon".
g) Transport protocol is udp
h) Caller ID can be left blank
i) Called ID Method is "From Username"
j) Call Waiting should be enabled
There is no failed registration retry timer setting in Groundwire.
