[cisco-voip] How can I maintain PSTN call during CCM <--> SRST mode change?

[Damien Ball]

Using MGCP with a PRI, can you maintain a call during failover?  I thought I read that you could not.

If using H.323 you can preserve calls on SRST fallback with the config
script below:
voice service voip
 h323
  no h225 timeout keepalive

I hope this helps.

Regards,
Khalid
