Thanks, I was able to achieve it with below steps.

$var(contact) = $sel(contact.uri); $var(alias) = $(var(contact){uri.param,alias}); $var(alias) = ";alias=" + $var(alias); replace_all($var(alias), "");

thanks, raj

We are using alias routing from NATHelper module and I’ve a case where the alias part ’alias=ip~port~transport’ needs to be removed from the contact header in 2xx message. There’s contact header reference “$ct” pseudo variable but it is read only. Is there any approach available to achieve this as I haven’t found anything in the forum archive search so far.

thanks, raj
