WIC-1DSU-T1 V2 Voice Compatibility

Good Morning Gentlemen

We recently setup a CUCM that is working fine and while going through my hardware inventory I noticed that I had a cisco 2811 router with a WIC 1DSU-T1 V1 card on it, this router is not in use  and I will like to start using this, so my brilliant idea (brilliant to me at least) is to set up the 2811 router as a mgcp gateway on our CUCM and use the T1 card to connect to a NEC system that has a t1 interface on it, I'm assuming that I only need to add a PVDM2-32 voice dsp module to the 2811 router to be able to use voice on this, is my assumption about this correct? will the WIC-1DSU-T1 V2 support voice (full t1) or is this wic one of those that only support data...

Thank you all for your support!!!

Hi Victor,

Sadly that module does not support voice T1/PRI;

"The T1 CSU/DSU WIC provides full or fractional T1 service. T1 CSU/DSU WIC does not do channelized T1 or ISDN Primary Rate Interface (PRI)."

Cheers!
