Hi, I have configured a phone DBC223 with two console with itype 30, on a card ELU28 / R2A but does not work. I have read the documentation that Alex card supports the phone in D4 mode from Release R3A. What exactly should I do considering that I can not replace the card, maybe upgrade the firmware of the phone? I thank in advance those who would help me.
Greetings.
