ipv6

IPv6 Certification Badge for timprovu

IPv6 is becoming a big topic at the moment.

We expect IPv4 addresses to run out this year. This isn’t so bad as we expect ISPs will start selling addresses to each other which will even out supplies for a few years.

But the future is IPv6. At ProVu we have had our network IPv6 activated for about 5 years. This has given us lots of experience.

We are also pushing all of our suppliers to update us on their IPv6 status. Ideally, all phones would support IPv4 and IPv6 dual stacked at same time.

We’ll update you as time goes on.

In the meantime, you could test your IPv6 connectivity using http://test-ipv6.com/

Disable SIP ALGs on Draytek Routers

Many commercial routers now a days are coming with SIP ALG`s turned on by default. This feature is suppose to help with Nat related issues but in majority it break the implementation and cause issues such as one way audio, lack of incoming calls, registration issues and etc.

Recently, We have received couple of calls regarding IP phones not working behind DreyTek routers. The reason is same SIP ALG.

If you are a victim of this feature please disable it using the following procedure.

Telnet into the router and enter the following command.

1. > sys sip_alg 0 — Disables sip alg

2. > sys commit — Apply changes

3. > sys reboot — Reboot router

Once router is back online, reboot the ip phone or press re-register.
