SV8100 SLT to DT700 No Voice

[GrizzLander]

Hello,

I'm currently trying to get a SLT line to talk to a DT700, which is being used as a call box. The SLT is assigned and when dialing the DT700 extension (or vice versa) the phone rings but when the line is picked up there is no voice from either end. Even when plugging a analog phone into the SLT card the same behavior occurs so I know it's not the call box being the issue. I'm guessing maybe there is some codec or relay issue but I haven't been able to narrow down the problem.

EDIT: Also to clarify I'm plugging the analog line into a LCA card.

Does anyone have any ideas? Thanks.

Do you have any digital multiline phones? Do they have the same issue?
MB 84-26 must be populated in the same subnet as 10-12-09. It is needed for voice communication to IP devices.

Thanks for your response. MB 84-26 is populated in the same subnet. I'm fairly certain that ML phones were working in my test environment but I only have a single phone at the site for testing, I'll have to setup a second to confirm this.
