Marco's Informatik Blog

Sto attrezzandomi per un altra iniziativa, ovvera la realizzazione di video corsi.
Per adesso ho realizzato un video per la creazione di un trunk custom su Trixbox, utile ad esempio per configurare un Patton qualisiasi.
Questo può affiancarsi alla guida che propongo con una piccola contribuzione, in alternativa alla guida cartacea + il file di configurazione del Patton.
Come esempio in questo caso uso Trixbox 2.6.0.7, se eventualmente siete interessati vi comunico “la contribuzione” su consulenze at ciacci.biz
Ciao!

Brevissimo post per dirvi che da qualche giorno è pronto (forse ha bisogno di qualche aggiustatina, ma mi pare che sia ok per le cose base!) il configuratore web per i Patton 4552,4634 e 4638.
Per maggiori info registratevi su www.ilmiovoip.com, il mio portale (nuovo e ancora acerbo!) dedicato completamente al VoIP.

Piccolo aggiornamento sul post precedente, ho dovuto fare una piccola correzione alla configurazione postata in precedenza, in quanto non era necessario dtmf-dialing, ed il sintomo che dava era curioso, ovvero il numero di telefono digitato da alcuni apparecchi collegati al PBX classico, erano “storpiati”.
Ad esempio se io digitavo 0577123456 questo mi diventava 0505777711223345455656 ad esempio!!!
Togliendolo tutto ok, inoltre ho creato un nuovo utente per usarlo come “friend” lato pbx ed inoltre ho aggiunto delle rotte per chiamare i cellulari, 8XX e 7XX

Tempo addietro ho fatto un post in cui parlavo dell’uso dei Patton SmartNode 4638 con Trixbox, in particolare una configurazione che prevedeva un 4638 collegato a borchie Telecom, un TRixbox in mezzo con funzioni di IVR ed un altro 4638 a valle collegato al vecchio PBX, con le porte in modalità NT.
Bene, la seconda parte della configurazione era errata, o meglio in parte, perchè è vero che le telefonate potevano transitare, ma solo impegnando la linea e poi alzando la cornetta, facendo subito il numero.
Mi spiego meglio…come voi saprete una periferica isdn, un TA con funzioni voce invia direttamente la stringa del numero impegnando il canale D, andando poi ad occupare il canale B al momento della risposta, mentre un telefono ISDN o un PBX si aspettano un tono libero, continuo o ritmato.
Per questo i toni italiani sono importanti nella configurazione, ma io non avevo tenuto conto di creare le tabelle di routing e i service di hunt group, quindi documentandomi sul sito Patton sono riuscito a fare una configurazione adeguata per questo 4638 a monte del centralino classico, ed eccola qua

Data la penuria su Intenet di esempi di configurazione funzionanti, propongo qui la configurazione di uno Smartnode 4552 presente nella sede remota di un mio cliente, quindi capirete il perchè delle regole di routing nel contesto router.
