First, disable the Windows firewall on your laptop, then try to download the default.dat file from the the SD card through eManager

Sometimes I would run a backup thorugh a phone instead of the laptop. That would rule out issues with your eManager. If it fails then it could be the SD card or the card slot on the processor. I think the maximum size that can be used for the SD card is 1 GB.

Hi all,

I’m working with an NEC SV9100 connected to a Grandstream UCM via SIP trunk. Extension-to-extension dialing between the systems works fine. The SIP trunks are set to DDI type, nec side

Now I want to go a step further:
I’d like extensions on the Grandstream UCM to be able to dial external numbers using the PRI trunk connected to the SV9100. Essentially, the UCM will send the call via SIP to the SV9100, and the SV9100 will route it out through its PRI trunk, with no other user interaction.
Has anyone set up something similar?
How should I program the incoming call on sv9100 to achieve this?

Thanks in advance!
