Detail information required "call preserve" and "no h225 timeout keepalive"

Hi can somebody explain me the diffrence b/w

"call preserve"   and "no h225 timeout keepalive"


Thanks in advance




  • Hello,


    call preserve and no h225 timeout keepalive are both used for the same general purpose, which is to preserve a call when the call processor goes down. h225 is limited however to only keep TDM-IP calls active. This means that all IP-IP calls will be dropped, regardless if the h225 command is used, whereas the IP-IP calls would be preserved if you used call preserve.


    Hope this helps.
