Callcentric has been putting out a series of service setting updates.

See:
https://www.callcentric.com/faq/51/554
https://www.callcentric.com/faq/51/552

One of the OPTIONAL updates is to change servers used from callcentric.com to sip.callcentric.net -- This is supposed to be for better service and security.

Please note that "callcentric.net" will not work -- the "sip." has to be in there.

As far as I can tell, the other updates for PBX Platforms with "Asterisk Configurations that explicitly define our Hostnames within the sip_custom_post.conf or sip.conf file" do not apply to Obihai.

My Obihai devices are not behind firewalls restricting their traffic.  If yours are, you might want to pay attention.

QUESTION: Does anyone see changes other than sip.callcentric.net that have to be made within Obihai configurations?  I don't.

NETWORK AND FIREWALL UPDATES
Deadline set for September 7, 2022

We've upgraded our infrastructure to enhance reliability, redundancy, and scalability. To ensure uninterrupted service, some customers (particularly IP PBX users) will need to update their equipment and/or firewall.

The deadline date to complete these updates is September 7, 2022.

Please forward this message to your network administrator.

WHO IS AFFECTED:
The large majority of customers (approx. 96%) do not need to do anything. This message and the required changes apply only to:

    Customers with a firewall that only allows access to specific Callcentric IP addresses
    Asterisk Configurations that explicitly define our Hostnames within the sip_custom_post.conf or sip.conf file

DEADLINE:
September 7, 2022

Callcentric support replied back:

Hello Michael,

No further changes are required. We see your Obihais are Registering over the new Domain.

Please contact us if you have any further questions. Thank you


Which I suppose implies that the new domain sip.callcentric.net would not register in the first place (even before their Sept 7th deadline) if further changes were needed on Obihai devices.
