I've setup MTP IOS in CUCM for MGCP T.38 faxing which is required for inbound faxing for Exchange 2007.
then create two MRG, one has IOS MTP and the other one has CUCM MTP. then create MRGL that has MRG (with MTP IOS) and MRG (CUCM MRG) respectively.
when I dial voicemail pilot number, fax is working but DTMF tone is not recognized. when I switch the order of MRGs in MRGL, then fax is not working but DTMF tone is recognized.
How can I setup MRGL and MRG that make both DTMF and MGCP T.38 faxing work at the same time?
any suggestion would be very appreciated.
