#2934 Phone dials while csipsimple menu choice is displayed

Hello.
Recent owner of an Alcatel Idol 4, i wanted to configure my SIP account... ok, nothing native, go for CSIPSimple!

Everything seems ok except one detail. When i dial from the phone, i have the choice menu from CSIPSimple displayed, but i see the phone is already dialing behind.
If i dial directly from CSIPSimple, no problem.

I tried to check the settings etc. but i have to admit i'm lost here. Did i do something wrong or it is a bug?
