reregistering phones in ccm makes 'em uncallable

[ThomasLiss]

Hi there,

I am a newbie with ccm, found help here before and am asking for help now again.

I managed to get VoIP working with CCM 3.3, phones 7960 and Cisco 1760 as gateway. Everything was (finally) working, inbound and outbound calling.
Initial setup of DN range in ccm was 10-19. Later, I wanted to change to 621-629. Changing the range of DNs in ccm and resetting the phones didn't help, they kept their old DN. So, I manually changed DN on the phones to 62X. Worked fine.
Later, I deleted the phones from ccm and let them reregister and they got DN in the new range.
After that, only one phone can be called from outside. When trying to call the others, I get immediately switched to secretaries through the pbx.

So, I can do internal calls by dialing only extension (621-629, ip-phone to ip-phone),

I can call outside with every ip-phone,

I can call any ip-phone from outside when doing so from another ip-phone and using full number (123456-62X),

but when trying to call from a normal phone plugged into the pbx to an ip-phone by using the external number (e.g. 123456-625), pbx immediately switches me to secretaries. That normally happens after 3 rings when nobody answers (pbx functionality).

One of the phones, however, is still callable (123456-622).

I thought I did something wrong in config of ccm. Checked everything, found nothing. So, I copied the config of the callable ip-phone (622) and reregistered another (625) with this exact config. No luck.
As you may read, I have absolutely no clue why one works and the others don't.
I'll post my router config here (the same config that worked fine before). If anyone has had this before or has a clue why this is so, any help would be greatly appreciated.

Thanks,

Thomas Liss

How is the PSTN sending the digits? Debug using the following command

debug isdn q931


Is your PBX sending digits to the PSTN and then the PSTN is calling your ISDN line? Or is your PBX connected to the 1700 router using the ISDN lines?

Try this.

Change your dial-peer voice 1 pots to

destination-pattern .

since all calls are incoming and not being sent to another call leg. The router could be getting confused on what it incoming and what it not. This is probably the issue.


It is what it is!!

I changed destination-pattern to ".", but that didn't help.
Our pbx guy was here today & found aprogramming error in the pbx. We will reboot that tomorrow morning and see...
Maybe it wasn't in the configuration of ccm/router after all.

I'll post results.

Thanks for helping,

Thomas

Gave you some bad advice (I was doing it from memory). Change it to this.


dial-peer voice 1 pots
incoming called-number .
direct-inward-dial
port 2/0


It is what it is!!

Hi,

Thanks again for your advice. I changed the dial-peer to what you suggested. That didn't help, but it couldn't have. PBX guy just called me, he did "some changes" to the configuration of pbx, now everything is working again.

Kind of reassuring.

Best,

Thomas
