+31 70 569 0105 / EPVPN REV0 (7380) | |
Status | In progress |
Contact | flimpie / eloy |
Last Update | 2024-01-27 |
Om voor in de toekomst(tm) gepruts met analoge telefoons mogelijk te maken is er een Asterisk bak ingericht, met daar aan een 070-nummer, een EPVPN-nummer en en een SIP2SIM (die zit in slot 2 van de spacetelefoon op de bar)
Gebruik
Om van buiten naar de space (via de asterisk-bak) te bellen: bel REV0 via EPVPN, of +31 70 569 0105.
Om vanaf de space naar EPVPN te bellen: bel 01999 + nummer via de spacetelefoon, en kies sim-kaart 2 (Vodafone NL)
Dialplan (op volgorde)
- `01999.`: naar EPVPN
- `+491999.`: naar EPVPN
- `+31[1-8].`: naar CheapConnect (om 0900 uit te filteren)
- `0[1-8].`: naar CheapConnect (om 0900 uit te filteren)
- terugvallen naar een 'dit mag je niet bellen' recording
