Tags: #VoIP
Model: Archer VR1210v  
Hardware Version: V2
Firmware Version: Archer_VR1210vv2_0.1.0_2.0.0_UP_BOOT_agc3000(240527)

I've bought the modem to use with my ISP TIM.

The connection work very well the problem is VOIP.

My ISP provided me the outbound proxy but the modem is not capable to resolve the IP address due the need of a DNS SRV request.

I've made it work doing on the PC a nslookup of type srv with _sip_udp prefix using the alfanumeric adress (_sip_udp.xxxxx.xx.xxxxx.xxxxx.xx) of outbound proxy to find an address, then a request of type A on that address to find an ip to put in the outbound proxy voip configuration and it work like a charm but is not an accceptable solution.

 

Is it possible fix this with a FW or i've to buy another modem?

 @Mrbean71 I've contacted technical support.

They provided me a beta FW to solve the problem and it has worked.

Hi, thanks for posting question here.

Upon checking, Archer VR1210v is a customized model by some ISPs only, we can know much less than common DSL modm routers.

For the VoIP setup, it is suggested to contact ISP or local support to feedback if our common guide does not help. Thank you.

@Marvin_S I think you make a mistake...

 

I've bought the router on a big e-shop.

And it is sold on internet every where.

I'm talking about this (Archer VR1210V) router:

I think you are referring to an another model the (vr1200v).....

I have the same problem with TIM. Is it possible to share the custom firmware? Otherwise, can you suggest where can I ask for it? Thanks, Luca.

  @Luca77 i've sent an e-mail to support.it@tp-link.com (the mail for technical support for private user).

Try and eventually resend it if they don't answer.

Ciao,

prova a chiamarli alle 9:00 di mattina (appena aprono) al numero HOTLINE SUPPORTO TECNICO che trovi in questa pagina:

 

Contattaci | TP-Link Italia

https://www.tp-link.com/it/about-us/contact/

 

A me hanno risposto subito e mi hanno inviato un firmware beta per il VX1810v V1 per  gestore TIM (aggiornato a febbraio dell'anno scorso) e le istruzioni per il VOIP.

In ogni caso, prima di chiamare, dato che mi pare che tu possa recuperare il firmware online (nel mio caso non c'è proprio la pagina dei firmware)  prova a configurare il VOIP selezionando


Other Provider (e non TIM)


e fai attenzione a configurare in IMPOSTAZIONI AVANZATE anche i parametri che vedi riquardati in rosso nell'immagine in allegato (corripondente alla UI del  VX1810v), ovvero


DSCP per SIP:                   CS5 (101000)

DSCP per RTP:                 CS5 (101000)

PCP per SIP/RTP:            5

che a quanto pare sono quelli che fanno funzionare il VOIP.


PER LA CONNESSIONE INTERNET
NON USARE DNS PERSONALIZZATI - USARE QUELLI DI DEFAULT

(I DNS personalizzato potrebbero essere una delle cause del mancato funzionamento VOIP)
 

Un'altra cosa: sempre nelle IMPOSTAZIONI AVANZATE io ho selezionato come Interfaccia Bound la pppoe_ptm_835_0, tu assegna l'id che viene  suggerito per il tuo tipo di connessione (anche se Any_WAN dovrebbe andare bene comunque).

 

Ti allego uno screen della UI VOIP del mio VX1810v con le indicazioni sui parametri da configurare

Hi, thanks for posting question here.

It is suggested to try firmware and check settings in the thread: Archer VR1210v V2 Fails to Register VoIP and Can’t Call in or out Normally under Italian TIM Line

Thank you and best regards.
