If I press the same number few times (like dialed 7 four times to mark the message read in GV), finally it understands. I already have this setup:
Service Providers -> ITSP Profile A -> General -> X_UseFixedDurationRFC2833DTMF : (checked)
Any consensus on build 2669? Does it work all the time? After I put the 2675 build, new VM indicators in my panasonic phone is working 100% of time. When I was on 2669, VM indicator was not working.
I guess, DTMF is more important than the VM indicator. If you call a number and it asks you to push another number - you are out of luck. Is it a GV problem or the OBI f/w problem?
