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
