I was testing an MGCP gateway, going from SRST mode, with switchback to MGCP where it re-registers to the primary CM.
Here is how I tested: I set up the command on the gateway for scheduled switchback, while doing the same on the gateway configuration in CUCM. I then proceed to test this.
The result: While in SRST mode, I set up a call from a phone that is in SRST out through the PRI interface on the SRST gateway. When switchback occursâ¦. The call is dropped immediately. However, the gateway follows the gateway setting: scheduled switchback.
It appears that the endpoint in MGCP always follows IMMEDIATE, while the gateway itself can be changed from Delayed/Immediate/Graceful/Scheduled. I would have thought that the endpoint would follow the gateway. However, this appears not to be the case. Is this how you understand this working? Or, am I missing a command or feature?
