Hi, I just setup SPA9000, SPA400 and a couple of SPA942/962 IP phones at my wife's small business. Our setup includes one ITSP line on Line 1 and a PSTN connection through the SPA400 on Line 2. Everything is working as expected except for the AA on inbound calls from the ITSP. After the call is transfered to an extension, that extension cannot hear the calling party. With inbound calls on the PSTN line, the issue does not exist.
I've tried to troubleshoot this for days and am stumped at this point. Has anyone incountered a similar issue and found a resolution ??
BTW, all the equipment is upgraded to the latest firmware release available on Cisco's website.
