VG410 analogue gateway ports locking

[JamesHawkins]

Hi,

I have configured a VG410 48 port gateway for use with CUCM. The CUCM cluster does not support the VG410 as an SCCP gateway so I have configured it as a SIP device and pointed a CUCM SIP trunk to it.

Calls seem to work ok but after a seemingly random period the phones connected to the FXS ports just hear re-order tone. It is not possible to dial between analogue phones connected to FXS ports on the gateway or to devices connected via the SIP trunk to CUCM.

Rebooting the gateway resolves the issue but it reoccurs after an hour or so.

Does anyone have any ideas on how to troubleshoot this? The gateway is currently running 17.12.04

Normally I would set the gateway up as SCCP but that would require an upgrade of CUCM to v14 SU3 or later which is not possible at the moment.

Hello, I am still seeing this issue with the 410 gateways and have tried four different software releases.

The gateways will work ok for several days but then the ports lock up. I have raised a TAC case but have not really had much useful feedback.

The VG410 does not have physical DSP chips - instead it uses virtual DSPs running on the main CPU. I think that this may be the root cause of the issue.

Has anyone else deployed VG410 gateways? If yes have they been working properly and would you be willing to share some info about software version and some configuration information?
