Solved: Re: Unable to configure voice ports.

john_earnest · ‎02-18-2010

CME 7.1 is running on my 3845. I have configured the Call Manager Express and calls are working internally. I recently installed a VIC2-2FXO card to prepare to getting outside line access.

"show diag" shows the card being in slot 0 WIC slot 3.

"show voice port summary" shows my voice ports being on 50/0/1-50. I know that after configuring an ephone, a voice port is automatically created.

"show run" does not reveal my FXO card.

Problem: "config t" , "voice-port ?" show my choice of being 50/0/1-50. I try to configure voice-port 50/0/1 and it says unrecignized.

IOS is c3845-ipvoicek9-mz.124-24.T1.bin.

How do I get my FXO card to work? Also, amber led lights are on the front of the card.

I've reinstalled the card and reboot my router several times.

John,

The HWIC slot does work with your card that's why it shows up in the sh inventory.

Perform the sh inventory again and look for DSPs in the form of PVDMs, NM-1V, NM-2V or NM-HDV. If you do not have any of these modules then you do not have any DSPs and that's why the voice cards do not appear in the config.

With voip you do not need to DSP chips for the voice unless you transcode between two different codecs, but once you introduce analogue ports then you need to convert the signals between the two with DSPs.

Cheers,

Phil
