How to modify Contact Header Field

[Rushikesh]

When I register a user, the contact header is set to user...@randomString.invalid  . But I want to change it after registration. After registration is successfull server sends the IP and port to the client. I want to use that IP value in contact header- for next client-server communication. How should I move to solve this?

Hi!

It is very easy, just set "contactName" in the UserAgentOptions object you're passing to the register command.

Here's an example from my code:

const userAgentOptions: UserAgentOptions = {

authorizationPassword: password,

authorizationUsername: username,

contactName: username,

viaHost: userDomain,

transportOptions,

uri,

delegate: {

onInvite: (invitation) => this.onCallRecieve(invitation, self)

}

};
