Bill Neely commented on ASTERISK-25933:
---------------------------------------

It is not really a great problem, just unusual. WHen registering this same phone to asterisk 13.2.0 and asterisk 11, the expires header is reported correctly. It is only in asterisk 13.8 and 13.8.1 that the expires header is overwritten to 30 sec
