Re: VG224 Issue with UCM7 & MGCP

Hi,

MGCP isn't the best solution with VG224

SCCP with VG224 is more recommended and stable beside the more features you'll benefit from it as suppplementary services for example

thanks

Re: VG224 Issue with UCM7 & MGCP

Are you sure you have all the correct dial peers? If you have 24 phones on this system, not all of them are registered.

Re: VG224 Issue with UCM7 & MGCP

It same seem stupid but have you rung the port with a phone in it? I`ve had it before where I got fastbusy until I plugged a phone in the port

You should listen to the advice by hythamhadad, switch away from MGCP and you shall be fine.

Re: VG224 Issue with UCM7 & MGCP

We had the exact same issue on several VG224. Turned out to be an IOS bug resolved in 12.4(24)T. Since upgrading to this release, we have not had this happen again. Prior to this IOS upgrade, only resolution was a to reload the VG224. A reset in Call Manager for a given port would resolve issue for a sort time some of the time.
