su tutti i fritzbox questa cosa è possibile farla, magari ansuel potrebbe riuscire a farlo per il modem tim

Ho provato a configurare il VoIP come sui fritzbox senza successo.. solo con i DNS di Tim funziona.. @FrancYescO @Ansuel

nclmrc commented 5 years ago

Sinceramente se usi per la wan i peer dns di tim, e nel dhcp metti i dns per la lan hai risolto secondo me.

Ghost9090 commented 5 years ago

Già quello lo so, ma è meglio averli anche sui dns internet invece di averli solo sul dhcp

kevdagoat commented 5 years ago

We could do this by creating an independent interface for VoIP (eg. voip_link) and then use dnsmasq or /etc/config/network to specify the dns server.

nutterthanos commented 5 years ago

Why would you want a different dns for your voip?

FrancYescO commented 5 years ago

Cause some (italian) providers of voip use fqdn, resolvable only from their specific DNS server.

nutterthanos commented 5 years ago

So the default dns server for voip on those gateways are like the isp one but they need a different one?

Temporary solution for TIM Italy (thanks @bandit400):

for i in $(cat /tmp/resolv.conf.ppp  | grep -v '^#' | grep nameserver | grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}');
do
  uci add_list dhcp.@dnsmasq[0].server="/telecomitalia.it/$i"
done   

uci commit dhcp
/etc/init.d/dnsmasq restart

An alternative is to append the auto discovered TIM DNS in /etc/dnsmasq.conf as follows:

server=/telecomitalia.it/85.38.28.4
server=/telecomitalia.it/85.38.28.5

85.38.28.4 and 85.38.28.5 are examples of possible TIM DNSs

After this step it is possible to disable Auto Discover DNS in Internet Access, set custom DNS, and VOIP will continue to work properly.
