[Asterisk-Users] Re: Again: 7920 Cisco IP Phone Skinny & SIP

Hi Jan,

>7920 how the callmanager is behaving.

I've just gotten one step further with my 7920: 
Got it successfully registered to asterisk. Still doesn't actually work, but
definitely a step in the right direction.

The problem is that the 7920 expects SelectSoftKeys Messages to finish its
setup - probably it sends the offhook/onhook sequence to trigger these.

Asterisk however doesn't send these until it's finished registering the
device on reception of a message of type 2d - which the 7920 never sends.

Hack/workaround, against current cvs:

-  sccp_dev_set_registered(d, RsProgress);
+  sccp_dev_set_registered(d, RsOK);
   d->currentLine = d->lines;

   REQ(r1, RegisterAckMessage);

This probably breaks all kind of other things, but it does let the 7920
register with asterisk.

Next Problem: Softkeys need special attention, currently the onhook/offhook
keys aren't mapped correctly, so you can't actually accept a call or hang up
:-) Dialing works bzw.

Bye, Martin
