[cisco-voip] 2800 as Data Router & VG - MGCP Bounces Data

[Carter, Bill]

I have a 2821 with 2 vwic2-2mftt1 cards.  The first VWIC supports 2
point to point T-1s running MLPPP.  The second VWIC supports 1 voice
PRI.  The Voice Gateway is running MGCP.  With ccm-config on the
gateway, a CallManager reset of the Gateway resets the voice AND data
ports!
 
Further complications....I tested SRST by inserting an access-list
blocking traffic from the 2821 to the CallManagers.  When the gateway
went into fallback mode, the 2 data T1 ports went out of service!
 
IOS 12.4(11)T3
 
Is this normal??  Do I need to switch to H.323?
 
Thx
