[Bug]: Contact header is not set by natPolicy or manually for register

[nigeldaniels]

Context

I use the linphone-sdk ( kotlin) for android. When attempting to register the Contact header field is automatically generated and not the correct one that should be discovered by my natPolicy

    private fun register(username: String, password: String, domain: String) {
        val mynatpolicy = core.createNatPolicy()
        mynatpolicy.isStunEnabled = true
        mynatpolicy.stunServer = "stun.gmx.net:3478"
        core.natPolicy = mynatpolicy

        val identity = Factory.instance().createAddress("sip:$username@$domain") 
        val accountParams = core.createAccountParams()
        accountParams.identityAddress = identity


        accountParams.natPolicy = mynatpolicy

        val authInfo = Factory.instance().createAuthInfo(username, null, password, null, null, domain)

        val proxyAddress = Factory.instance().createAddress("sip:$domain")
        proxyAddress?.transport = TransportType.Udp
        accountParams.serverAddress = proxyAddress
        accountParams.isRegisterEnabled = true
        accountParams.natPolicy = mynatpolicy
        val account = core.createAccount(accountParams)

        core.addAuthInfo(authInfo)
        account.contactAddress = Factory.instance().createAddress("sip:[email protected]")
        core.addAccount(account)
        core.defaultAccount = account
    }

In the above code you can see I try to use both nat policy as well as manually setting contact address neither seems to work I am trying to understand what I am doing incorrectly

logs of the register msg that is generated is provided bellow
