TLS sips: prefixes break callingNumber and calledNumber

[lylepratt]

These two functions require sip: prefix and don't work with TLS's sips: prefix.

  Object.defineProperty(this, 'calledNumber', {
    get: function() {
      const user = this.uri.match(/sip:(.*?)@/) ;
      if (user && user.length > 1) {
        return user[1].split(';')[0] ;
      }
      return '' ;
    }
  }) ;
  Object.defineProperty(this, 'callingNumber', {
    get: function() {
      const header = this.has('p-asserted-identity') ? this.get('p-asserted-identity') : this.get('from') ;
      const user  = header.match(/sip:(.*?)@/) ;
      if (user && user.length > 1) {
        return user[1].split(';')[0] ;
      }
      return '' ;
    }
  }) ;```
