    My VOIP provider needs me to remove the a=T38FaxMaxIFP setting to allow incoming faxes to function. It seems the recent upgrade to Version 15 added this new parameter.

    When I removed it from the Settings / Parameters list, it still came through, but with a different value (200). Is there a way I can remove this parameter entirely?

    After Removal:
    a=T38FaxVersion:0
    a=T38FaxRateManagement:transferredTCF
    a=T38MaxBitRate:14400
    a=T38FaxMaxBuffer:1800
    a=T38FaxMaxDatagram:150
    a=T38FaxMaxIFP:200
    a=T38FaxUdpEC:t38UDPRedundancy

    Before Removal:
    a=T38FaxVersion:0
    a=T38FaxRateManagement:transferredTCF
    a=T38MaxBitRate:14400
    a=T38FaxMaxBuffer:1800
    a=T38FaxMaxDatagram:150
    a=T38FaxMaxIFP:40
    a=T38FaxUdpEC:t38UDPRedundancy
