On other Yealink phones(newer firmware), I can configure the call pickup string as a separate value. In our case it is *8. On older firmware like the VP-530, we simply add *8 in the extension box on the BLF config screen. This has always worked in the past for T-2x series phones and T-3x series phones.

The first difference seems to be that I must put the full *8{extension} in the extension field for the VP-530 to attempt to dial the correct *8{extension} string. Once it does try, it fails to dial due to an "unknown uri scheme". I believe I have captured this, and I can see the incorrect URI in the level 6 logs:

So, what I am seeing, is that the ";BLF-Index=2" is not stripped from the end of the sip: invite string. This creates an invalid server address, and the phone cannot attempt the pickup call.

I'm worried that this may never be fixed, as this phone no longer appears to be getting firmware updates. Is there anything we can do to work around this?
