SX20 and ISDN Link with TC6

Adrian Lazar

Hi guys,

I have recently upgraded an SX20 and ISDN Link to the new TC6 and after the upgrade I cannot make ISDN calls anymore.

I can see and manage the ISDN Link from the SX20 configuration web page but the status of the ISDN Link is: Error , SIP not registered.

I am using H323 in the network and I only use SIP between the SX20 and ISDN Link and with the old version I was able to receive and make calls. Now when I try to dial ISDN using the new TC6 interface the endpoint says that it does not find the ISDN Link.

Thank you for your assistance,

Adrian

Thanks Patrick and Valentin

I removed all the dummy SIP configuration and used the H320 protocol to dial out and it worked. I was able to call my mobile.

So if SIP is not used anymore between the SX20 and ISDN Link this means we can safely disable it on the SX20 Network Services ?

Regards,

Adrian
