I have a 2821 with a vwic-2mft-t1 card connected to my Nortel switch, using QSIG. When calling from my 7960 phone into Nortel, the name display is not shown. Works using DMS100.
Any ideas ?
You need minimum of 12.4(9)T for qsig decode, eg I have that working with a matra pbx.
DMS100 passes names via q931 display IE that is a simpler protocol.
Hope this helps, if so please rate post!
