Hello,

There are 20 7921 almost all phone iis baak to 1.3.3 but there are two phones hasnot been downgrade to 1.3.3 i could not find why these phones does not downgrade to 1.3.3.
What can i do ?

The 3.x 7921 hardware requires 1.3.3.0.3 ES or later.
You can ask TAC to provide 1.3.3.0.3 ES or our latest ES (1.4.1.1.1.7), which the 1.4(2) release will be based on, which has more aggressive scanning than previous builds (1.3.4 - 1.4.1SR1).
If you have further questions, just ping me back.

Hi Mike,
You mention that there is a an ES 14.1.1.1.7 that will map to an upcoming 1.4(2) release.
I have a client that is running 1.4.1SR1. I thought that 1.4.1SR1 maps to ES 14.1.1.1.7?
They receive inbound calls on their 792x phones and the phone only reings once even though the call is still being presented to the phone because you can see the LEDs flash and you can still take the call after it stops audibly ringing.
I see a bug in the 1.4.1SR1 release notes: CSCtj21700 that seems to be a close match.
TIA

Yes 1.4.1.1.1.7 is based on 1.4(1)SR1 plus a few more fixes and changes.
But the 1.4.1.1.1.7 has enhanced scanning. Also 1.4.1.1.1.7 does not support interband roaming.
The official 1.4(2) release will include seamless interband roaming support, which is based on the 1.4.1.1.1.7 plus a few extra fixes.
Like I mentioned on the other thread, if it is CSCtj21700, then there is no audio not even a single sound while ringing in and won't have audio when the call is connected. This requires a power cycle.
This is a rare situation and only seen at a few deployments.
So if it is a case of only ringing once, but then audio is fine, then it is the following issue.
CSCto03375 7925 Ring Delay issues with certain ringtones
But either way, both CSCto03375 and CSCtj21700 are resolved in 1.4.1.1.1.7 ES and will be resolved in 1.4(2) as well.
See the following thread for more info.
