[cisco-voip] Disconnect of calls when switching to SRST

[Erick Bergquist]

This is working as it should after I had chance to get
copy of config. Was set to immediate for switchback
mode. Also, for T1/E1 PRI calls that are MGCP
controlled those will be dropped when going to/from
fallback. Only analog and T1 CAS calls are maintained.


Thats from this cisco doc:
