Store and Forward fax T.37 over SIP trunk on CME 8.6
My company utilize CME 8.6 with SCCP phones , 4 analog POTS line true FXO/DID ports .
CME is configured for UM on Exchange 2010 for voice mailboxes and store and forward fax messages with IVR ON-RAMP TCL script.
Everything working fine, incoming FAX messages coming to email of users.
Yesterday company move to another location and we get SIP trunk instead 4 POTS analog lines.
Without problems we configure CME for using SIP trunks for voice calls,
but I do not know if it possible to configure CME to use “store and forward faxes (T.37) for calls received true SIP trunk.
I temporally attach old G3 fax machine to FXS port , now I receive faxes over fax pass-through mechanism but users want fax messages forwarded to their email mailboxes
Does anybody know if is it possible to use ON-RAMP scripts on CME for call received from SIP trunk .
And if so could you be so kind to help me. Please!
I presume that is possible and I need only to forward incoming calls. It was easy with POTS I just needed
voice-port 0/0/3
connection plar opx 777
caller-id enable
every call received on dedicated analog line CME forward to number 777
dial-peer voice 5002 pots
service onramp
incoming called-number 777
direct-inward-dial
port 0/0/3
then DID and IVR onramp to STORE fax
dial-peer voice 5001 mmoip
service fax_on_vfc_onramp_app out-bound
destination-pattern 777
information-type fax
session target mailto:ciscofax@mydomain.com
and call app to FORWARD fax
now I have dial-peer for incoming calls with IVR scrip how will change called number to extension number
dial-peer voice 5000 voip
service toroute
session protocol sipv2
session target sip-server
incoming called-number 11223344556677
voice-class codec 1
voice-class sip dtmf-relay force rtp-nte
dtmf-relay rtp-nte

T.37 is not supported on VoIP trunks, because in such calls there is no DSP available for the function.
You can configure T.37 on the PSTN gateway, and it will work the same.
