Unanswered Question
Oct 30th, 2007

Hi, Here is the scenario. A single site IPT where gw is using h323. If I have "no h225 timeout keepalive" configured in h323 gw, an acive call is established between pstn and ip phone, if ccm fails, will the call still preserved? thanks

I have this problem too.

You need to perform a few extra steps:

On the router,

voice service voip

h323

call preserve

then on the call manager (in my case 4.1)

Service -> service parameters -> advanced

Then under H323 set "Allow peer to preserve H323 calls"

After doing all of that try a test call and block access to the CCM via an ACL - phone should display "CM Down, features disabled" but the RTP stream should continue between the phone and router.
