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
