I'm trying to set VOIP on VF-NZhg556, the VOIP account is the free one from 2talk, phone number start by 028, I will buy the 10 dollar plan if the VOIP does work on my moderm


The thing is I can't press save bottom after fill in my SIP ID, User name and password on SIP User paper.

The save bottom is clickable but not able to save any data on SIP user page but it does work on SIP Server page




I did my setting follow by these steps:
1. Login using the vodafone admin details 
user:admin 
pass:VF-NZhg556 

2. Goto Voice->SIP->SIP Server 
SIP Server (dropdown) = Primary Server 
SIP Proxy Server Address = sip.2talk.co.nz 
SIP Proxy Server Port = 5060 
SIP Registrar Server Address = sip.2talk.co.nz
SIP Registrar Server Port = 5060 
SIP Service Domain =sip.2talk.co.nz 

Click "Save" (do not click Save/Reboot) 

3. Goto Voice->SIP->SIP User 
SIP Account = SIP 1 
Enable Flag = Enable 
DO NOT TICK "Active SIP Account" 
SIP ID = 028xxxxxx 
User Name = 028xxxxxx
Password = xxxxxxx
Leave all other settings as is 

Click "Save" (do not click Save/Reboot) 

Now, it may autocorrect and put vodafone.co.nz on the end (mine did), just re-type and save again. 

4. Leave web admin open, then Telnet to your router 
user:admin 
pass:VF-NZhg556 

Type this into the prompt: 

voice set all enable (then enter) 
save (then enter) 

This part sets that "Active" checkbox in the webadmin that refuses to tick 




Is there anyone had this kind of issue before?
