Description:An error message is shown when a Subscription request is sent with an Expiration time of 0 set.

This shouldn't be an error, it is in fact an 'unsubscribe' event and asterisk should expire the subscription when receiving this type of message.

This message will occur if a SUBSCRIBE is received out of dialog with an expires of 0. In this case the message is correct: res_pjsip_pubsub has no idea about the subscription or the SUBSCRIBE is formatted improperly. This message WILL NOT occur if a resubscription or unsubscribe occurs in-dialog.

Do you have a SIP trace showing this occurring?
