Cisco CP8800 series ip phone access web interface.

Hello,

Recently purchased a Cisco CP-8861 IP phone that was advertised as specifically designed for 3rd party call control. I started up the phone and it automatically went to an expressway sign-in app. I was able to locate the IP address of the phone and tried accessing the web interface by simply typing in the ip address as typically done with other models. While the phone responds to pings it refuses any connection attempt using it's ip address.

I've looked at all the documentation online numerous times and while I've found several others with the same question I haven't found any answers. I'm wondering if it has to do with upgrading the firmware? If so, can it be done without use of CUCM? I see that a TFTP server might help but I want to make sure that's the issue before doing the upgrade.

My current firmware is sip88xx.10-3-1-20

I really hope there is something simple that I'm overlooking!

Well I had my hopes up that it was fail2ban but I disabled it and still no joy. Is there a way to ping the phone from within Asterisk? I tried using the CLI but it doesn't seem supported. It would be very surprising if they couldn't talk to each other but at this point I can't think of anything else blocking the phone from registering.

You mentioned that more information may help. I have included the SEPMAC.cnf.xml file below, the reported phone settings, the extension settings in asterisk, and also the phone status messages upon startup. Please let me know if you think anything else would be helpful.

It also might be worth mentioning that the phone still hasn't seen an address listed in the active server category either.

NAT Mode: Yes - (force_rport,comedia) (also tried no)

Set this to "NO" and force the phone to erase the config and reboot.

<transportLayerProtocol>2</transportLayerProtocol>

Set the value to "0".

Highlighted

Thanks, I'll give that a try in the morning. What does 0 represent? I found documentation for 1,2 and 4 online but not 0.

Highlighted
Hall of Fame Community Legend

0 means UDP

1 means TCP

2 doesn't exist

4 means TCP &/or UDP but it doesn't work.

Highlighted

I tried both the suggestions and neither of them worked. The only transport number that got through the "Phone is registering" screen was 2.

When you say "force the phone to erase the config and reboot" does that entail something besides modifying the cnf.xml file and restarting the phone?

Every time changes are made on the SEPmacaddress.xml.cnf file, the IP phones needs to be factory reset.  The phone needs to have a factory reset because, with newer 9.X phone firmware, the phone will only download this file ONCE.  

Thanks, I'll give that a try in the morning. What does 0 represent? I found documentation for 1,2 and 4 online but not 0.

My sincerest apologies, I am confused.  The setting should be "2" for UDP.  Please make the correction, erase the config of the phone and reboot the phone.  When the phone reboots it should download the corrected SEPmacaddress.xml.cnf file from the TFTP server.

Highlighted

That's weird, I saw changes take effect after modifying the cnf file and just restarting the phone. I'll give factor reset a try.

Highlighted

No worries about the confusion, I've tried 1-4 and only 2 gets me passed the expressway sign-in screen. I did upgrade FreePbx to 13 in hopes it was just a bug with 12 but that didn't work. Right now I'm wondering if it's a NAT issue, which would be strange since the network is small and simple at this point. It sounds like others had issues but nothing to the extent I'm having.

I'm getting a SPA504G shipped from another office to test out, if that doesn't work then it's something bigger than just the phone config.

I am a bit confused on the endpoint manager templates. I use the CP9971 as it sounds like the closest match. I wouldn't imagine this to be the case but would a mismatched template cause the server not to connect?

I'm wondering if it's a NAT issue

Disable NAT between the phone and the Asterisk. 

Can the phone ping Asterisk (and vice versa)?

Highlighted

I've tried initiating ping from Asterisk CLI and it says it's not an available function. Is there a way to do it from the phone side?

Highlighted

I read somewhere else in a post a few years ago that modifying the sip.conf file was necessary with "cisco_usecallmanager=yes".

Is this patch old or still required? First time I have heard about it and will be trying it in the morning. If it is valid, are there any other modifications to this file that I need to make?

Highlighted

I don't remember doing this but try it.

Highlighted

I'm currently on freePBX 12.0.76.2. Would updating to 13 potentially help?

Highlighted

Is there a way to ping the phone from within Asterisk? I tried using the CLI but it doesn't seem supported. It would be very surprising if they couldn't talk to each other but at this point I can't think of anything else blocking the phone from registering.

Is the phone and Asterisk server on the same IP address subnet (highly recommended)?
