we found that with many of them the SCCP CCM did not match the CMG on the VG224's. What I was also wondering is, do the device pool information on the lines have to have the same CMG as the VG itself ? We started changing it so that we have 1 device pool per VG but I have 50 of these, so is it a must? They ran for years with mutiple device pools pointing to multiple CMG groups per VG224 so this is whay I asking. ( I didn't build them I got stuck with them)

We recently upgraded from CUCM 6.15 to 7.15 and none of the analog gateways worked afterward. in order to get them to register ports we had to change the SCCP cm to match the CUCM group in Call Manager. On others we had to change the CUCM group to sum 1-2 or 2-1 no other group would work. Once i did this the ports registered, but I was told that the CUCM group on the ports must match the CUCM group on the VG224. This has worked for years with the mismatch and once I upgraded the code to 15.1.4(M2) they would work of changing the CUCM group. The ports show rejected after upgrade, registered before upgrade but not working. Another issue we have is and it may be related is some phones are now showing rejected and even if we rebuild them the mac address still will not work. I believe this is some kind ofl replication issue after the upgrade Any thought s would be appreciated.
