Asterisk 20 Presence with snomD717-SIP 10.1.141.13

Hello. After following various documentation on SNOM website, I can't get Presence working despite the fact that SIP logs on D717 shows that xml events are sended by the other subscribe phone (which is a snom760-SIP 8.9.3.80). Using BLF is working as expected.

D717 is 115, 760 is 105 in Asterisk dialplan. Subscribe context is:
[MySubscribeContext]
exten = 105,hint,PJSIP/abcdef_105&Custom:DND105,CustomPresence:105
exten = 115,hint,PJSIP/abxdef_115&Custom:DND115,CustomPresence:115

On D717 I used the third Smart Label button and put it in XML Definition using following xml pasted in the Number area (copy taken from modified parameters in configuration state)

As you can see, event is sended to the phone but nothing happend on the led.   Same if 105 is Ringing, nothing happend on 115 even *8 does'nt intercept the call. Also, putting phone in DND does'nt send NOTIFY, is that correct?

What am I doing wrong (if) and how to get Presence working properly with SNOM phones ?

Thanks for your support, any hint welcome
