Error registering linksys SIP phones on CME

Answered Question
Oct 4th, 2010


I have some Linksys SPA941 and SPA921 SIP phones and I'm trying to setup a CME on a 2811 router with IOS: c2800nm-ipvoicek9-mz.124-24.T2.bin

The problem is the phones won't register on the CME, I also tried using X-lite and no luck either.

I keep getting this error:

VOICE_REG_POOL: Register request for (cisco) from (
VOICE_REG_POOL: Invalid destination pattern (cisco)

Here is the relevant part of my running-config:


ip dhcp pool VOICE
   lease 0 0 30

Can anyone help me out please?
