Sustituir router vodafone / comunitel con VoIP por cisco 827, 17xx o 18xx

Esto es una config que tení­a hace tiempo.
Comunitel o ahora vodafone / tele2, cuando instalan un ADSL, los teléfonos tienen que ir conectados al router ADSL, con lo que es, a la práctica, VoIP.
Es un proveedor bastante cerrado y no es facil que te den los datos de conexión, pero tras mucho insistir los he conseguido.
El motivo de cambiarlo es que, necesito hacer una vpn y me gusta tener controlado los dos extremos, asi que procedemos y para ello necesitamos:
1º) usuario / password VoIP / ADSL
2º) IP’s gatekeepers
3º) Ip de VoIP
Partimos de la base siguiente:
1º) Dividen la conexión ADSL en 2 circuitos: circuito 1 datos, circuito 2 voz… así­ se aseguran que la voz tenga su caudal.
2º) En mi caso tení­a un telsey con 2 bris (rdsi), así­ que la configuración para analógicos difiere un poco, aunque no mucho.
3º) La conexión es pppoA y o sé si es correcta, pero mí­ me ha funcionado.
4º) La voz, debe de ir «exclusivamente» por el circuito de voz, así­ que la deberemos encaminar con un route-map.
Una vez tenemos estos datos, vamos a configurar nuestro router, sabiendo que el circuito ATM es PPPoA. En mi caso he usado un cisco 1760:
