Using CallManager 7.1(2a) I hit bug CSCsy29533 with T38/MGCP in 12.4.24T1 and had to downgrade to 12.4.15T6.
In 12.4.24T1 I had;
sccp ccm 10.10.10.21 identifier 1 priority 1 version 7.0+
Once I downgrade to 12.4.15T6 I don't have that version option, seems to default to;
sccp ccm 10.10.10.21 identifier 1 priority 1 version 3.1
What is the ramification of using the wrong version? Will this ever be auto-detect? I have IOS Enhanced Conference Bridges in 2821s registering with CallManager at remote branch sites. Will using version 3.1 cause problems with 7.1(2a)? What version keyword should I use with 7.1(2a) and 12.4.15T6?
