| 
| 
| Hi,
| 
| The " draft-ietf-sip-refer-06.txt " says that the duration of 
| the subscription is determined by the expires parameter in 
| the Subscription State header of the first Notify. [Section 3.4].
| 
| Does that mean the the first Notify 'MUST' have an expires 
| parameter in the Subscription State header ?? 
| 
| If not, what should be the duration of the refer-subscription 
| ? There is no default value suggested.
| 
| 
| Regards,
| Reshmi
