Linksys PAP2 - Billion 7300G incoming calls to voicemail


Just changed router from a speedtouch 780WL to a Billion 7300G as I was getting too many dropped connections with this router (bethere Pro)

I have a Linksys PAP2 adapter which was working fine before the change

I have re-setup the adapter using the voipfone auto setup

incoming calls are going straight to voicemail
Outgoing calls are working fine

I have setup DMZ on the router for the Linksys adapter which hasn't helped

I also have a sip phone which is working fine no issues

I did contact Billion but they said that I need to use a STUN server which isn't required for Voipfone

Can someone please advise where I'm going wrong



I had a billion router, i gave up on it 3 weeks later. Nothing but problems and not just with voip! :cry:

Sorry if this is not much help to you but i tried loads of things but nothing helped, billion were not much help either. With any luck someone will be along soon who may have a solution.

I wish you luck! :?

Hi acoolwelshbloke

I don't think that it is an issue with the router, probably just a setting on the adapter that needs tweaking

What issues were you having with the Billion Router ?



Following the information here you should be able to get into the settings area - Please set 'use outbound proxy' to 'yes' and save. Then reboot the PAP2 (power off for a moment, then back on)

If incoming calls still do not work please email us at support at

Thanks for you reply

I did change the 'outbound proxy' to 'yes'

Prior to 'outbound proxy' to 'no' the phone used to ring but you couldn't hear the caller & the caller would get voicemail

When I changed the 'outbound proxy' to 'yes' the phone doesn't even ring & simply goes to voicemail

I have worked out that the router is blocking ports

If I DMZ the PAP2 then everything is fine
The problem then is I can't get the sip phone to work & vise versa if I DMZ the sip phone, the PAP2 has the same issue

I've tried opening all the ports range on the router but still no luck

If there were 2 DMZ options, I could resolve this issue but there isn't




Problem has been resolved with Firmware upgrade to V1.38-c-689-80.3
With excellent support from Milton @ Billion

Voip now working fine again :)
