Does h323 channel work with cisco 2600 with faststart?

Hi All,

My test bed is Asterisk->Cisco 2600 IOS 12.3. Asterisk h323 channel configured enable faststart. Cisco 2600 also works with another Cisco gateway with faststart.

In my test case, the Cisco 2600 gateway always sends back fastConnectRefused and does not use faststart.

Does any one have experience to make Asterisk and Cisco gateway working with faststart?

Thanks.

The h323 channel driver I referred is chan_h323.
