Via,Route,Record-Route,Contact(incase of Register) etc can have multiple numbers in a msg.

But no such rules for TO and FROM headers.

Please refer 3261 for more understanding of all the headers.

Thanks

Hi ,
As per the below answer, the ROUTE header present in more than one and VIA header also.
 So any special rules for  TO and FROM headers.
