I had some problem with my phone T26P. it send PRACK retransmission even if it received a 200 OK response.(dunno if its a bug or it's caused by packet lost)

depending on the sip server this causes the server to send a 606 Not acceptable an the call was drop.

So i decided to turn off PRACK in the config menu.
I found the option "Retransmission" in Account-->Advanced. The describtions says "Enable/Disable PRACK transmission". But regardless of the choice i made the phone always sends "Supported: rel100". A SIP server could answer with "Require:rel100" in the response. So if deactivating PRACK the phone shouldn't send "Supported: rel100"

i am running but it also happend with
