From Kolmisoft Wiki

Image:audio.png SYSTEM ERROR. CODE 200. The system cannot determine who is calling.

The IP from which the call comes is not entered in the system or is entered incorrectly. 
Some other fields in configuration may also be missing. 
Please consult the online manual at wiki.kolmisoft.com.

[edit] The Provider/Device is not authenticated

  • Check settings for Provider/Device.
  • For provider - make sure hostname and IP address have correct values.
    • Both these fields should be filled.
    • If hostname is not assigned, then it should have an IP address, with the same value as the IP address field.
  • Check the port setting.
    • The call may not be coming through the default SIP port 5060, but from 5061. Check this.
    • Port refers to the SOURCE port. That means the port the call is coming FROM, not the port it is coming TO.
  • Make sure that originator is using same protocol as it is configured in Device/Provider in MOR. Means, make sure that it is not trying to make H323 call while Device created in MOR is SIP type.
  • If you are using H323 in file h323.conf, add UserByAlias=no.
  • If you are using ZAP/H323 provider, you may have forgotten about the accountcode=X setting. (More info)
  • Make sure accountcode for dialing device is not 0 (ERROR[3433]: app_mor_authentication.c:11 mor_get_user_by_acc: Accountcode cannot be 0!)





[edit] The Main Reason

You forget to describe IP in MOR from which the call is coming.

Example:

[Dec 17 08:37:42] WARNING[21726]: app_mor.c:3557 mor_get_user_by_acc: User not found by accountcode:
[Dec 17 08:37:42] ERROR[21726]: app_mor.c:667 mor_authorize: MOR can't determine who is calling. Make sure accountcode is set for caller (Provider or Device).
[Dec 17 08:37:42] NOTICE[21726]: app_mor.c:692 mor_authorize: Caller type: Local

[Dec 17 08:37:42] NOTICE[21726]: app_mor.c:3900 process_sipchaninfo: Contact: sip:7052058393@64.34.164.254

[Dec 17 08:37:42] NOTICE[21726]: app_mor.c:3907 process_sipchaninfo: ==========================================

The above means that MOR does not know about IP 64.34.135.88.

SOLUTION: assign this IP to some Provider (or Device) in MOR.


The most common reason why people get this error

The reason is, that very often MOR administrators forget about Trustrpid, Sendrpid, Insecure: port/invite options in device settings window. They must match incoming call settings. The image below shows settings that are usually correct.

[edit] How to disable such call attempts

By default MOR allows guest calls (unauthenticated calls) so the calls would be processed and would show up in the STATISTICS->Calls->Last Calls after they are rejected and the Admin could see such call attempts as well. This is very useful when you are trying to setup a new device and the call does not go through due to bad authentication. However, you can disallow such calls to be processed at all by changing the "allowguest" option in sip.con file. To do so, simply open the sip.conf file with any editor(in the example we will be using "vi")

vi /etc/asterisk/sip.conf

Then find the allowguest option and change it to:

allowguest=no

After this save the file and reload asterisk so new setting would take affect:

asterisk -rx 'sip reload'
