TUTORIAL IP-based authentication VOIP.MS

[redstonemason]

I searched the forum here but did not find an answer even though it might be staring me in the face

Had a problem with a password being hacked on the weekend. Although VOIP.MS were good to me and credited a good chunk of the 200 U$D damages in Toll Fraud, I am moving to whitelist for my external extensions and making sure that VOIP.MS authenticated my accounts for my PBX trunks by IP address (their whitelist).

Question:

Do I just remove the text in the Register String field to enable IP based authentication.

It seems to work but I do want to make sure I am doing this the correct way.

Looks like they documented the procedure here: http://wiki.voip.ms/article/PBXs#Asterisk_IP_Auth._.28SIP.29

Asterisk IP Auth. (SIP)

This page talks about setting up the sub accounts for it: http://wiki.voip.ms/article/Sub_Accounts

sip.conf

Note: You'll need to create a sub account to use IP Auth
[voipms]
canreinvite=nonat
context=mycontext
host=atlanta.voip.ms (one of our multiple servers, you can choose the one closer to your location)
type=peer
disallow=all
allow=ulaw
; allow=g729 ; uncomment if you support g729
nat=yes



extensions.conf

[mycontext]
; Make sure to include inbound prior to outbound because the _NXXNXXXXXX handler will match the incoming call and create a loop
include => voipms-inbound
include => voipms-outbound

[voipms-outbound]

exten => _1NXXNXXXXXX,n,Hangup()
exten => _NXXNXXXXXX,1,Dial(SIP/1${EXTEN}VOIPMS)

In the FreePBX World, Chris's sip.conf info would go into your SIP trunk settings. The other contexts would go at the bottom of extensions_custom.conf. VoIP.ms signup link from Nerd Vittles.
