So we just moved from AT&T to Windstream as our PSTN. With AT&T we had a traditional TDM PRI, hooked to a TMDI card in the switch.
With Windstream, this is a Dynamic IP service run into a Adtran router, then out a TDM T1 port as a PRI.

We are having issues with timing. The clock goes in and out of error trying to sync to the line. Of course this is not Windstreams issue, even though it had been working for years with AT&T.

They are also having issues when dialing into IVRs. They do not outpulse any DTMF now. Not that the DTMF is distorted, it just isn't even there.

Has anyone run into this before?
