Is there any command to force a Cisco SIP Voice Gateway (VG) router to use Delayed Offer. I am using IOS Version of 12.4(22)T on Cisco 2811 Hardware. The basic requirement is that to demonstrate that Cisco Router can be configured for both SIP Early Offer and Delayed Offer.
Pls Note that there is no CUBE component involved.
