[hylafax-users] Erratic DTMF / DID information

["Cannon, Greg" <GCannon@xxxxxxxxxxxxxxxxxx>]

Title: Erratic DTMF / DID information

We have set up everything for fax routing based on inbound number called.  The call goes through our Avaya IP Office PBX,  The DID information is sent to the modem via DTMF and picked up by HylaFAX as callerID information and routed to the proper mailbox.

The problem is the callid0 value is right about 85% of the time.  The other 15% of the time, instead of getting 4344, I am getting: 444, 34, 44, 434, 344 or 43.  This doesn't appear to be effected by "<delay:100>" in the device's config file.

I know this is the Enterprise version of HylaFAX and I fully expect to contact the ifax guys with this, but first I wanted to run it through here in case someone has seen it before and knew it to be a modem firmware issue, a configuration issue in IP Office, timing or even could suggest ways to narrow it down.

Server version: HylaFAX Enterprise Version 2.4.3 (hylafax-enterprise 2.4.3-1rhel4)
OS: CentOS 4.6
Kernel: 2.6.9-67.0.7.ELSmp
Modem: RockForce Quatro+ board Rev 1.2
Modem firmware: Mainpine Venus V.92 I03.04.02 (0021) Voice V2 V92cap 12ns RAM Mercury
PBX: Avaya IP Office 406 version 4.0 (10)

My config.device file is configured with:

ModemRingResponse:      AT+FCLASS=8;H1
CallIDPattern:          SHIELDED_DTMF
CallIDAnswerLength:     4
ModemAnswerCmd:         <delay:100>AT+FCLASS=1.0;A

An example session log:

Any help would be greatly appreciated.

Thanks,
