Re: Requirement for PRI ISDN E1 to IVR

Hi

You would need an E1 VWIC, with DSPs. Assuming one port (one E1/30 channels) will be enough, you would require:

VWIC-1MFT-T1/E1 <--- E1 VIC

PVDM2-32 <--- DSPs for the VIC

In terms of IOS, you would need a feature set that supports Voice.

So at least IP Voice, or one of the other feature sets listed as inheriting voice features at this URL:

How the the IVR connect to the router? SIP? H.323?

Re: Requirement for PRI ISDN E1 to IVR

Hi

VWIC2-1MFT-T1/E1 is the one you want - the other will be a data-only card.

You use the same hardware/software for SIP/H.323, I was just curious. Would suggest you get the hardware, search for some config examples on Cisco.com, and post back a new thread if you have issues...

Re: Requirement for PRI ISDN E1 to IVR

Hi

I would go for the VWIC2-1MFT-T1/E1 - it's basically the updated version of the VWIC-1MFT-T1/E1, which is a little old and is going End-of-Life.

http://www.cisco.com/en/US/prod/collateral/modules/ps3129/prod_end-of-life_notice0900aecd806c3dc6.html

Apologies for the confusion, typed the parts from memory.

Both the parts would work in your router/scenario, and both would require the PVDM2-32 and Voice IOS.

Re: Requirement for PRI ISDN E1 to IVR

Ok thakns very much for your help

what is the rule of the PVDM2-32 card

the VWIC2-1MFT-T1/E1 cannot work without PVDM2-32 ?

Re: Requirement for PRI ISDN E1 to IVR

Hi

Yes - that's more or less it.

Each channel of voice (running G711) would require one channel of DSP to run. So if you have a 2-port VIC2-2FXS for example, you would need 2 channels of DSP. You require more for advanced/compressed codecs.

As your E1 has 30 channels, you need 30 channels of DSP. So the smallest you can use is a PVDM2-32. It's supplied in the form of a small module (like a memory DIMM) which you install internally in the router.
