Hello Grandstream Support

Have problem call inbound display unavailable. configure sip trunk account
UCM6304A

  1. call from +85581551713 to +85523890500 and then display unavailable

Means nothing we can help with unless you tell us how the UCM is configured to look for CID and how you have confirmed that provider is sending the desired detail.

Dear user,

Thank you for using the UCM63xx! This is depending on why they transmit “unavaiable” to this UCM device. You can capture the trace file and syslog from the peer SIP server and send the logs to us for troubleshooting. Thanks for your testing!

Thank you!

Dear user,

Thank you for your feedback! We checked the given logs and the “Unavailable” is received in the UCM63xx, so it is not an issue in the UCM63xx. You may need to check why the remote client sends the “unavailable” to the UCM63xx. Thanks for your testing!

Thank you!

Dear user,

Thank you for your feedback! You can try to modify the CallerID Name so that all inbound calls will be named as your configuration. Please refer to the screenshot below:
%E5%9B%BE%E7%89%87

Thanks for your testing!

Dear support

I have follow this but the display is test&phone number (change from unavailable to test).
what do have any solution?

#11

Dear user,

Thank you for your feedback! Yes, this is the normal behavior. Since the UCM63xx is the receiver, so you may need to focus on why the sender sends “unavailable” to the UCM63xx device. This should not be an issue on the UCM63xx side. Thanks for your testing!

Thank you!

Dear user,

Thank you for your feedback! Could you please tell us what you would like to display? The UCM63xx receives the inbound as “unavailable”. May I ask if you have checked with the service provider? May I ask why the service provider sends the “unavailable” in this case? Thanks for your testing!

Thank you!
