Registration cache and the presence of cookies.

Hi Everyone,

I have a quick question regarding the presence of cookies in the output of a  "show registration sipd by-user 98450081@abc.net detailed" command, and why this command may be different across a 4500 and a 4250.

 

On the 4500 I see the following -note the bolded cookie that is appended to the number in the SD info section

 

 

NIL-SBC05# show registration sipd by-user 42291814@arrow1.co.nz det
