I have a little problem on my SX20 TC7.3.1 with my ISDN Link IL1.1.3.
This is the error message i have: Not Sip-Registred to H320 Peripheral.
Someone told me it was probably because the SX 20 is in Gatekeeper instead of "direct" and probably SIP deactivated.
Can anyone help me with that problem?
could you tell me if you are running encrypted TC software or not ?? log into your web interface and look at software version. capture it and uploaded here as attachment if you can.
If your SX20 is running on non-crypto software you might be hitting this bug - CSCul19957
But as you mentioned you're running TC7.3.3 which is a crypto version there should be no issue. There might be missing in your configuration.
Things to check:
Even if IPv4 is selected, the ISDN Link will use IPv6 link for local traffic with the paired codec when operating in auto pairing mode (default). It is important that the paired codec also allows IPv6 link for local traffic, otherwise it will fail to pair with the ISDN Link.
Are you using manual pairing mode or auto?
This error is commonly seen when SIP Outbound is turned ON in the codec.
If you are seeing the error Not SIP-registered to H320 peripheral then you need to make sure that SIP is turned ON and that SIP outbound is OFF on the codec.
