[c-nsp] 2821 voice configuration

[Bernhard Schmidt]

Hello everyone,

we want to use a Cisco 2821 as SIP-PSTN media gateway and PRI switch for
a slow migration from an old PBX to a VoIP PBX (Asterisk)

	| E1 carrier
 +------+-------+
 |  Cisco 2821  +---- IP/SIP to Asterisk
 +------+-------+
        | E1 old PBX

Required key feature is forwarding of calls between all three legs,
especially transparent E1-E1 (using dial-peer statements). We have this
setup running for more than three years on AS5350XM with a lot more E1
lines so I'm pretty sure how to configure that, but I have never done
this with 2800 series and I don't want to buy anything we can't use
afterwards.

We want to use

CISCO2821-V/K9		2821 Voice Bundle,PVDM2-32,SP Serv,64F/256D
VWIC-2MFT-E1		2-Port RJ-48 Multiflex Trunk - E1
PVDM2-32		32-Channel Packet Voice/Fax DSP Module

can anyone see any reason why this might not work?

Thanks,
Bernhard
