Hi All
today i was upgrading a7400 with 150 itp phones to allow for the connection of a conf24 card

I upgraded the mp40 from 4.30d to 4.53c and the lp40 to 1.27 after a couple of tests i realised there was only on way speech on calls(PRI) okon internal so i tought the MGI16 should also of been upgraded but i couldnt FTP onto the MGI16 card and also wasnt quite sure of the procedure and as i didnt have a spare card i aborted and downgraded the MP40 back to 4.30 i left the LP40 the same (1.27) but the 2 way speech came back (TG)any help or ideas on the correct way to upgrade the MGI 16
thanks
