Hello,<br><br>I'm using Thomson/Technicolor ST2030S hardphones with Asterisk 1.6.<br>Changing from 1.6.1.18 to 1.6.2.6, I can see a change in Pickup's behaviour and I'm a bit confused about it.<br><br>With 1.6.2.6, when extension 7791 is calling extension 7792, I can see INVITE messages coming in and out Asterisk.<br>
I can also see a NOTIFY message advertising this call to subscriber 7793, for instance.<br>Here is an extract of this message :<br><br>NOTIFY sip:7793@192.168.101.102:5060;user=phone SIP/2.0<br><snip><br>Call-ID: <a href="mailto:7019-c0a80101-d-3@192.168.101.102">7019-c0a80101-d-3@192.168.101.102</a><br>
<snip><br>Content-Length: 212<br><br><br>From then, if BLF 7792 on extension 7793 is pressed, then an INVITE message is send with :<br>INVITE sip:*87792@192.168.101.240:5060;user=phone SIP/2.0<br><snip><br>Replaces: <a href="mailto:pickup-9582-c0a80101-d-4@192.168.101.102">pickup-9582-c0a80101-d-4@192.168.101.102</a><br>
<snip><br><br>This Replaces header refers to RFC3891 which is not yet supported in Asterisk (see <a href="http://www.voip-info.org/wiki/view/Asterisk+SLA">http://www.voip-info.org/wiki/view/Asterisk+SLA</a>)<br><br>
This INVITE fails with :<br><snip><br>chan_sip.c: Trying to pick up 7792@subs<br><snip><br>app_directed_pickup.c: No target channel found for 7792.<br><br><br>If I'm dialing *87792 instead of using BLF, then I'm entering the dialplan part in which there is Pickup(${EXTEN:2}@PICKUPMARK) and the call is correctly pickup.<br>
<br><br><br>So my understanding is :<br>when upgrading from 1.6.1 to 1.6.2, Asterisk must somehow advertise a newly supported SIP capability which is now used by ST2030S hardphones to build Pickup requests.<br><br>My question is :<br>
- is my understanding correct ?<br>- if positive, is there a way to tame asterisk to behave appropropriately ?<br><br>Regards<br><br><br>
