Siccome mi piace complicarmi la vita ho voluto usare due 1751V tra loro ma non riesco a far funzionare il secondo. Dunque il primo è collegato ad internet e tramite una WIC 1Enet ho collegato il secondo 1751V alla Fastethernet ma non funziona (il secondo router monta una CME 4.1 con collegati due telefoni in SCCP. Ecco un pò di configurazioni:

Grazie mille a tutti

ho collegato il secondo 1751V alla Fastethernet ma non funziona

Puoi essere più specifico? Il fisico ti sale? mettendo due ip statici i router si pingano?

Saluti

allora avevo abbandonato l'idea dei due router e in realtà mi ero anche arenato. Adesso utilizzo un 1720 che serve a far navigare i computer in internet e dalla WIC 1Enet vado al 1751V che dovrebbe fare da centralino (spero di riuscirci, prima o poi) ed ecco le configurazioni:

Il problema è che il secondo router non effettua le chiamate e pure collegando un pc ad una porta della Vlan non si naviga, la cosa che mi mette dei dubbi è il fatto che il sip-ua si registra!!! Potete aiutarmi???
