Rodrigo you speak spanish ? because my english is very poor.

Te lo digo en español: se puede hablar a otro dominio pero no directamente
con el numero sino de esta manera:

usuario A (100) de dominio1.com = 100 at dominio1.com <mailto:100 at dominio1.com>


usuario X (1001) de dominio2.com = 1001 at dominio2.com
<mailto:1001 at dominio2.com>  

 

entonces si queres llamar al usuario 120 de dominio2 tenes que marcar
120 at dominio2.com <mailto:120 at dominio2.com>  esto se ve facilmente usando
softphones, por ej. el de xten que te permite ingresar caracteres tambien.

 

Porque algunos telefonos ip son muy complicados para marcar @dominio

Otro ejemplo seria por ejemplo con pwlver y sipphone

17475000 de sipphone quiere llamar a 47568 de pwlver, entonces tiene que
marcar por ej: 47568 at fwd.com <mailto:47568 at fwd.com>  y asi marca al numero +
dominio y el sip server lo manda a donde marcó y no busca el numero 47568
dentro de su dominio porque lo daria seguramente como erroneo.

 

De todas maneras a veces por medidas de seguridad se puede restingir este
trafico, para evitar que usen otros servicios en vez del que uno tenga.

 

Saludos, Cristian

Hi.

 

Let's suppose we have 2 SIP domains:  D1 and D2.

If there is an user U1 registered in D1 and another one U2 registered in D2,
with U1 unknowing about U2's address and U2 unknowing about U1's address, it
probably will be necessary to use a SIP Redirect Server to U1 find U2 and
vice-versa, like a read in some RFC.

 

But, who is the responsible for recording valid data into the SIP Redirect
Server? Is it need to use DNS while recording data in a SIP Redirect Server?

 

May I implement an application responsible for talking with proxies from
these domains, collecting and exchanging data from their respectively
Registrars?

Is it possible in theory?

 

Thanks a lot!

 

Rodrigo.
