[cisco-voip] alarm panel issues and VG224 w/ SCCP

[Fuermann, Jason]

The head end is probably hanging up while the dialer is still spitting out codes, and the gw thinks it’s trying to dial an extension. Just a guess.

Subject: [cisco-voip] alarm panel issues and VG224 w/ SCCP

We have a remote site which uses alarms on their VG224. It seems they're not working properly. I've got a call back into the client to arrange a conference call with their alarm provider so I have access to technical details I can share.

When I look at the CDRs, I see some strange entries. Basically a call to a toll free number, followed by short calls of 1 second with invalid DNs. (see below)

I recall some talk about alarms and SCCP and it's better with MGCP. Can anyone who had this problem confirm if this was the same issue?

I have no problem setting up a few ports for MGCP but I have some concerns:

 *   can I have a VG224 with some ports as SCCP and some as MGCP?
 *   how can I ensure that my MGCP ports work during failover, i.e. SRST?

    *   I don't want to have to redo all my dial-peers. I don't mind putting in one dial that sends all calls from the VG224 to the SRST router, but I'd like an inbound dialpeer from the VG224 that assigns the same class of service for all inbound calls from that vg224.
    *   Is this doable?
