Cisco 2821 : Configuration

Unanswered Question
Apr 28th, 2009


Since I wasn't able to make the fax working good on my 2801, I m trying with another IOS but on another router (2821)

It's not the first use of this router, but I can't test now in another configuration.

Here are a part of sh ver :

Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9-M), Version 12.4(9)T, RELEASE SOFTWARE (fc1)

Cisco 2821 (revision 53.51) with 249856K/12288K bytes of memory.

2 Gigabit Ethernet interfaces

2 Channelized E1/PRI ports

1 Virtual Private Network (VPN) Module

DRAM configuration is 64 bits wide with parity enabled.

239K bytes of non-volatile configuration memory.

62720K bytes of ATA CompactFlash (Read/Write)

So I m trying to report my configuration from my 2801 to this 2821.

But I haven't the command voice-port in this 2821, is that normal ?

I'm not usual with telephony thing...

I have this problem too.

You will only see "voice ports" when you configure pri-time slots on your gateway. The voice ports are automatically created.

Post a copy of your config here

You need DSPs to terminate voice calls. If you do a show diag, you should see if you have DSPs on your router or not

No DSPs on this router.

Just buy one PVDM2-32. Will try after the delivery. Thanks for your help.
