> The only change I saw, is that with 1.6.1, when Asterisk receives a BLF-generated INVITE *8142, it enters appropriate context and extension and now, with 1.6.2, it doesn't though it still accept hand-typed *8142 sequence.<br>

</div></div>The difference is in the NOTIFY where you will get identification for the INVITE. Because of that, I guess that the INVITE for the call pickup has a Replaces: header. That will change the logic quite a lot.<br>
</blockquote><div><br>Yes, you're right : I remember that when I quickly looked at INVITE message (the one that failed), I saw a Replaces: header I was not familiar with.<br>I don't know yet if directly dialing also produces this header so I can't say if the resulting behaviour depends or not of phone behaviour (using Starcodes, I hoped to get rid of phone specific implementation).<br>
