Rispondo a damiano: il fax non riceve neanche e posto sotto il file di log di un tentativo di chiamata dal fax della mia collega (dice anche in questo caso che è busy):

Ho tentato anche di modificare i valori di DTMF ma credo che sia impossibile provare tutte le combinazioni, mi spiego meglio: l'opzione nel fax è denominata "DTMF" e al suo interno posso scegliere tra un range di valori che va da 1 a 15 sia per il DT che per il MF. Ho fatto tutte le prove con tutti i valori di DT e per il MF ho tentato solo per valori tra 1 e 8. Mi sono fermato scoraggiato perchè credo che se la prova debba avere un senso allora dovrei tentare tutte le combinazioni. Ad es. per il valore 1 di DT devo combinare tutti i valori da 1 a 15 di MF e viceversa... E quando finisco? :S
Allora ho preferito verificare anche ciò che mi è stato detto da donbru01 e posto sotto il risultato del log del 3cx:

stando a quello che dice donbru01 sembrerebbe che la chiamata fatta dal fax non venga tracciata, giusto? E cosa significherebbe?
Verifica se il modulo ATA ha un debug e syslog su cui inviare degli eventi
Il Patton Cisco SPA 112 non ha un syslog e quindi non posso fornire ulteriori delucidazioni...
Grazie a tutti anticipatamente!
