Can't change voice LAN on CME v8.6

[Alex Deiwor]

Hi,

I have a Cisco 1861 Integrated Services Router using the voice service, with 3 VoIP phones.

At first, I made a  configuration with a LAN voice 172.22.0.0/24, working everything OK.

I'm trying to make a second configuration, with a LAN voice 172.16.0.0/24 using the previous config, but this does not work.

I see how the DHCP service provides the correct IP address to each phone, but when I try to use the phone, is sounds a continous beep.

I attach the configuration config I made. May be I forgot something to execute, but as I told before, If i replace all 172.16.x.x to 172.22.x.x it works. That's driving me crazy.

Thank you.

Hi Alex

Your question isn´t clear for me, I don´t understand your setup.

Please correct me if i´m wrong, you have a Voice network with IP 172.22.x.x/24 and is trying change that IP range to 172.16.x.x/24 right?

From your config i was unable to find the range 172.16.x.x/24, just found that 172.16.0.0/12. Check both the DHCP and Phone and confirm if the correct mask is assigned to.

If yes try change the command in the telephony-service session source ip source-address 172.16.x.1 port 2000.

I hope this help

Hi,

Thank you for your reply. You're right, I'm trying to change the voice range from 172.22.0.0/24 to 172.16.0.0/24. Notice that the voice VLAN has no VRF. The range 172.16.0.0/12 you checked is a data range from one of the clients I have set up one VRF called green (Verde). As i told before, the phones receives the IP trhu DHCP, but can't finish the whole configuration

Well, I modified the config as I think it would be correct, I list the changes (The whole config is attached).

The last option I keep in mind is that may be have to rebuild any configuration that the IP Phones have to download.

Hi Alex

I´m assum that was working before with IP 172.22.x.x, right?

Anyway try reset the Phones to factory default and do a no create cnf-files and create cnf-files.

[Alex Deiwor]

Hi,

Yes, the configuration works correcty if set 172.22.x.x as voice VLAN.

I'll try to rebuild the cnf-files, because it's the last thing i have to try.

I'm a little scared about rebuild this. Next monday I have to make a conference with the equipment, and  don't want damage the actual working configuration.

Anyway, tonight i will try that. Thank you Bruno!

Hi,

Problem solved. If I change the LAN range, i've to create the cnf files.

Thats a little bit disturbing, because my objective is to load different configs with the command

copy flash:configNEW.conf startup-config

and now I have to rebuild manually that files.

Edit: I forgot to add the command telephony-serivce > create cnf-files

Well, I had a last question, but i try to google it. sometimes when I create the cnf files, the router shows that message:

Cisco-1861VOZ(config-telephony)#create cnf-files

Creating CNF files

CNF-FILES: Clock is not set or synchronized, retaining old versionStamps

But the clock  is up to date

Cisco-1861VOZ(config-telephony)#do show clock

*00:24:34.795 UTC Wed Oct 10 2012

Cisco-1861VOZ(config-telephony)#

Any ideas?

Thank you!

I reply to myself:

The following message:

CNF-FILES: Clock is not set or synchronized, retaining old versionStamps

Is due to i had no the specific clock configuration entered as configuration terminal mode.

In other words, setting up the clock is not enough, also its needed the following config:

Clock configuration

router# config t router(config)#clock timezone ESPANA 1 0 (Spain as my country) router(config)#clock summer-time ESPANA recurring router(config)#clock calendar-valid router(config)#telephony-service (Now create the cnf files) router(config-telephony)#create cnf-files Creating CNF files router(config-telephony)# (created with no sync error!! Let's check it out) router(config-telephony)#do show run | i cnf create cnf-files version-stamp 7960 Oct 10 2012 00:45:35 router(config-telephony)#

It's done, Bruno, so many thanks for your support!
