Come da oggetto avrei l'intenzione di configurare 2 o più interni con telefoni SCCP che possano fare e ricevere telefonate da e verso il mondo esterno utilizzando un trunk SIP di un account Messagenet.
Con Trixbox ci sono riuscito in 4 click, qui la faccenda si complica un poco.
Innanzi tutto mi devo chiarire alcuni concetti.
1) Devo creare un dial-peer per ogni ephone? Se ne acessi 100 la faccenda diventerebbe ingestibile
2) Il telefono è un 7940G con fw SCCP, ma il dial-peer lo devo creare come POTS ???
3) Ho visto qualcuno che mette le credenziali di accesso all'account sip nella dichiarazione del dial-peer.....Pensavo si dovesse dichiarare una sip-ua e poi usare quella e basta.
4) Per il dialplan peggio che andar di notte. Ognuno sembra che faccia in modi diversi. Io avrei bisogno del classico "Per uscire metto lo ZERO davanti al numero e via"
5) Per ricevere invece i telefoni interno squillano tutti assieme, il primo che risponde prende la chiamata...
Che fatica eh ? .-)

Dopo alcune prove sono riuscito a registrare il numero:
Cisco1751V#sh sip-ua register status
Line peer expires(sec) registered
============ ============= ============ ===========
201 20013 62 no
538XXXX 20015 834 yes
Chiamando da fuori sento il segnale di libero ma l'Ip phone non squilla.
In compenso vedo che l'interno 201 tenta di registrarsi su messagenet mandanto un messaggio REGISTER tipo questo
From: "201" <sip:[email protected]>;tag=1311B740-16CE
Ma utilizzando il SIP-UA come mai gli interni associati al telefono tentano di registrarsi ??

Qualche idea?
I punti 1, 2 e 5 credo di averli (forse) risolti.
Per il dialplan ho impostato un destination-pattern 9.T
però niente da fare, dopo lo scadere del timer oppure l'invio del carattere # sento inesorabilmente il segnale di occupato.
Con un pò di debug sono riuscito a vedere che in uscita il router tenta di chiamare tutti i numeri con il prefisso 9 davanti...(!!!!!)
Ma non dovrebbe togliere il pattern impostato da comando ????

Risolto, ora riesco anche a chiamare fuori. Il destination-pattern è stato aggiornato a .T anche se premendo i tasti di linea ottengo subito il tono classico di portante presente metre vorrei sentirlo solamente dopo aver digitato la cifra per esterno es il numero 9.
Il problema maggiore è che riesco a ricevere telefonate dall'esterno entro qualche minuto dalla registrazione al registrar sip messagenet. Dopo più nulla.
Quando perà scade il tempo di registrazione (impostato a 3600) il tutto ritorna a funzionare per qualche minuto, e così via.
