+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

Bijbehorende infra

revphone.flimpie.net

Debian 12 bak, draait Asterisk. eloy en flimpie hebben toegang. ssh'en naar poort 20422


Configuratie

[inbound]
; the generic inbound call context. if specific treatment (like CID translation) is needed per trunk, create a separate context and let it call 'inbound' using Gosub
exten => s,1,NoOp()
exten => s,n,Log(NOTICE, Incoming call from ${CALLERID(all)}, cid num ${CALLERID(num)}, cdr ${CDR}, all cid ${CALLERID(all)}, dnid ${CALLERID(dnid)}, exten ${EXTEN}, to ${PJSIP_HEADER(read,To)})

exten => s,n,Hangup()
exten => s,n(closed),Playback(sorry)
exten => s,n,Playback(nbdy-avail-to-take-call)
exten => s,n,Hangup()

[inbound_epvpn]
; rewrite the CID, prefix it with 00491999 if it is from inside EPVPN, if it's from the EPVPN DID rewrite it to a proper public phone number
rewrite CID before handling as normal inbound call
exten => 7380,1,Set(OLDCID=${CALLERID(all)})
; if the caller number starts with 0000, it's from the DID, rerite the number
; if it doesnt start with 0000, it's internal to EPVPN so only rewrite the number and keep the name (may be set by caller and is used by some phones)
same = n,ExecIf($["${CALLERID(NUM):0:4}" != "0000"]?set(CALLERID(num)=00491999${CALLERID(num:1)}))
same = n,ExecIf($["${CALLERID(NUM):0:4}"  = "0000"]?set(CALLERID(all)=<00${CALLERID(num):4}>))
same = n,Log(NOTICE, Rewrote CID for EPVPN call from ${OLDCID} to <${CALLERID(all)}>)
same = n,Gosub(inbound,s,1)
same = n,Hangup()

[inbound_pstn]
; rewrite CID before handling as normal inbound call
exten => s,1,Set(OLDCID=${CALLERID(all)})
exten => s,2,Set(OLDNUM=${CALLERID(num)})

; extremely bodgey, but the gist of this is that it will rewrite local numbers to +31 numbers, rewrite anonymous CIDs to +31979999999999 (a bogus number, I don't know how A&A expects anonymous numbers)
exten => s,3,ExecIf($["${CALLERID(NUM):0:2}" != "00"]?ExecIf($["${CALLERID(NUM)}"  != ""]?ExecIf($["${CALLERID(NUM)}"  != "anonymous"]?set(CALLERID(num)=0031${CALLERID(num):1}))))
exten => s,4,ExecIf($["${CALLERID(NUM)}" = "anonymous"]?set(CALLERID(all)=+3197999999999))
; another pain: numbers starting with + aren't handled properly
exten => s,5,ExecIf($["${OLDNUM:0:1}" = "+"]?set(CALLERID(num)=00${OLDNUM:1})))
exten => s,6,Log(NOTICE, ${OLDNUM:0:1})

exten => s,7,Log(NOTICE, Rewrote CID for PSTN (CheapConnect) call from ${OLDCID} to <${CALLERID(all)}>)
exten => s,8,Gosub(inbound,s,1)
