Ah, there's no description on the firmware download page describing what each firmware version is for. I have actually tried 25.73.193.40 and started working my way backwards in version numbers to see if it was just a firmware issue revision.

I'll regenerate the traces using the latest firmware for you.

No, the only Yealink handset is 72033. It doesn't matter whether the other parties are Cisco IP phones or PSTN numbers. The behaviour is the same. As mentioned from a SIP trace perspective it all looks fine however the call terminates instead of completing successfully.
