Hi there !
Having problems with Untangle + freephoneline + magicjack plus...
I have a Grandstream HT286 (ADVANCED SETTINGS 1):
SIP Server: voip.freephoneline.ca
Outbound Proxy: voip.freephoneline.ca
By the way: sip.fongo.com = voip.freephoneline.ca
SIP User ID: your_phone_number
Authenticate ID: your_phone_number
Preferred Vocoder (put them in this order. works for me anyway): G729, G726-32, G723, PCMU, PCMA, iLBC, G729
local SIP port: 5666
local RTP port: 5777
Use random port: No
SIP Registration Failure Retry Wait Time: 5
NAT Traversal: Yes STUN server is: stun.xten.com
keep-alive interval: 10
The rest to defaults...
Maby ADVANCED SETTINGS 2, NTP Server: time.nrc.ca
I know, it's a untangle forum... ;p
And with Untangle
On a 100$ used 3GHz dual core / 2 network card / 4Gb ram (more then enough !).
Advanced, general: No Enable SIP Helper
Port forward (use the same ports than in the device): 5666 and 5777 to your device IP. Do a reservation in your dhcp if needed... I do have a magicjack plus (that is not as reliable as the freephoneline) at the same time and I don't want port conflicts.
Bypass rules: "From device ip" and "To device ip". Check also Bypass VOIP taffic (SIP and IAX2)
QOS - You have to play with it... My inet access is 30Mb in / 2Mb out, so:
Default priority: Medium
Download: 25000kbps (I'm reserving for other stuff also)
QoS custom rules: "From device ip" and "To device ip": Very high. I also put my NAS at low qos
Not a bad thing to reboot your untangle after the config... The current connections have to be killed to get the new qos setting...
Stop whining with your crappy "soho" home router that freeze when you torrenting and get Untangle ! ;p
Hope this can help someone
