I have the following setup
VCSc (ver X5.2) connected to (SIP<->SIP) Codian MCU 4505
The zone on VCSc has the following setup
On the MCU the sip trunk has the following setup
when i dial the MCU on the VCS i get the following error
In the logs of the MCU i can see the call coming across. I also see the error:
|SIP||Error||Registration lost - server error code 403|
over and over again...
Any help would be great!
so your default subzone (Or possibly another subzone which this MCU will be a member of) is set to 'Check credentials', yet you have not configured a password on the H323 settings page on the MCU.
To resolve this, either add credentials for the MCU in the VCS local database (Or LDAP if you use that for authentication) or configure your Default Subzone with an authentication setting of 'Treat as authenticated'. Please note that this will disable authentication for registrations on your VCS-C, allowing any user to register without credentials.
Is there a reason why you want to run the MCU with SIP only. Did you try with h323 only+interworking on the VCS?
What version do you run on the MCU? I would also look into upgrading to a later VCS version.
What is the encryption policy on the EX90? Do you force encryption?
Can you try to call from the EX90 with disabled encryption?
Btw, you should see that you get/install the encryption key for the MCU and use SIP-TLS.
