Hi Team Experts,

If I check the log and find that after continuos switching users login and then calling I get call crash in this function as highlighted line below.

Also the log in the console gives this message:

Subject: [Linphone] Implemented Logout but app crashed on calling with other user name

Hello Experts,

I am facing one issue, I have mentioned the  steps so the issue is understood and helped to fix.

1. I login using One username and password
2. Call --> All Ok
3. Logout --> This is not there in SIP so have implemted following code to reset linphone as below

    [self destroyLibLinphone];

    [self createLinphoneCore];

    

    // reset network state to trigger a new network connectivity assessment

    linphone_core_set_network_reachable(theLinphoneCore, FALSE);

1. Call again login with another user 
1. Till the SIP address passed to the function (- (void)call:(NSString *)address displayName:(NSString*)displayName transfer:(BOOL)transfer {
   ) all is okay but the app gives me EXCESS – BAD ACCESS at line (linphone_call_set_user_pointer(call, data);
   )
2. If restart the application It works fine with second user logged in.
3. I assume that some where I am not resetting the linphone settings back to the way as Application starts. 

Please help me to get hold of this issue as to how I can reset all settings same as the application starts.

Thanks,

Regards,

Vicky Dhas
