[cisco-voip] strange shared line behavior on 88XX phones

[Lelio Fulgenzi]

turns out it is written.

Shared Line Restrictions 

The following restrictions apply to shared lines: 

<snip> 
•Do not configure shared-line appearances on the primary lines of the phones; for example, if two phones have a shared-line appearance, only one of the phones should have the primary line configured as shared (the other phone should have the secondary line configured as shared). 
<snip> 




In version 10 it becomes a suggestion though. Interesting.

Shared Line Suggestions 
Do not configure shared line appearances on primary lines as certain feature interactions are impacted. Settings of the primary line are applicable to the shared line. For example: if two phones have a shared-line appearance, only one phone should have the primary line configured as shared to avoid unexplained post configuration behavior.

It is on a fair number of them. They didn't have the issue on 8.6.2 with the same firmware. 

We're waiting on the next occurrence to gather traces.

I recall there being an (un)written rule where shared lines should not be the primary line. It could cause issues. 

Are the shared lines the first DN on the phone?

anyone seen issues with the 88xx phones on firmware 10.3(1) and CUCM 10.5.2 SU1 where the line starts ringing on some phones right away and some start ringing up to 15 seconds later. Some also experience ringing after the call is answered up to 15 seconds after answered. 

88xx phones are the only ones exhibiting this behavior. Another consideration is that this shared line is on 17 devices. 

Thanks for any insight!
