SIP/VoIP accounts could not be modified if not deleted, and doesnt allow to connect

since few weeks Im wondering about that feature, it appears that on last phosh version, a sip/voip account management module is available firstly thank you for this. but in a way, where I try to use it, I have two problems : a/ I cant change parameters while profile is just created, I always have to delete it and recreate it for any modification b/ when I open phone app, I have a one second red error message telling me its unable to connect ; thus, in the sip account list, the account profile is always in "offline" button and I cant pass it online

well, I added everything here : https://www.amazon.fr/clouddrive/share/GE5DmfKGGOfM4RqTFgbmCEIzHsrdfiuWQQFzA59MUg9

thank you !
