I'm expecting to buy a e65 nokia mobile, and configure a SIP acount with asterisk. But i have a fear: I'm going to buy the e65 mobile to a telephone operator (because it's cheaper) and maybe the SIP, and VoIP settings are blocked by the operator.
Is possible that it happens?
Can i avoid this great inconvenient?
If i update the firmaware, is the VoIP service also updated, so that i can avoid the inconvenient?
Thanks very much
