No disconnect for RTCP ?

Hello there!

I'm still rather new to data networking as my professional job, but I'm improving my understanding quite fast. :-)

I'm 1st time here to get advice from you, gyus.

I have this problem and don't understand why it acts the way it does. Imagine a H.323 scenario, where I have 2 routers C1750 w. VIC-2FXS having live telephony connection between themselves. This connection was established using gatekeeper residing somewhere in the network. After a while I disconnect a serial link from one router. The parties don't hear each other. When I connect it back after few seconds (e.g. 10), the conversation can continue!It's NOT torn down !!! Really strange...

As far as I know, RTP runs on top of UDP, and RTCP on TCP. So, RTCP should be responsible for determining such event and behaving appropriately - tearing down that call (maybe after a time) and causing gateways to genarate tickets sent to RADIUS.

A will be thankful for all your hints (whether CLI or not) and doc references.
