[cisco-voip] H323 Enhanced Call Preservation and Media Inactivity Detection

[Brian Henry]

Remember to also change you service parameter in CCM to allow the call preservation as well.

Well, because we're single threaded over the WAN, our situation is that
we lose connectivity to _all_ CMs, not just one.

Did you try pulling your "WAN" connection instead of shutting down a CM?

We use:

voice service voip
  fax protocol pass-through g711ulaw
  h323
   call preserve limit-media-detection
  modem passthrough nse codec g711ulaw
!
!
voice class codec 1
  codec preference 1 g711ulaw
  codec preference 2 g729r8
!
!
!
voice class h323 1
  h225 timeout tcp establish 5
   call preserve

works on 2851 / 12.4.9(T)
