ELCE11: Till Jaeger on AVM vs. Cybits

In general I'm very fond and impressed with the AVM Fritz.box DSL
routers, doing ADSL, ADSL2+ and VDSL. Here in the Netherlands one of
the largest and most savvy ISP's XS4ALL has all its DSL customers
running with the Fritz-Box 7340, which also does Internet VoIP
telephony. This gear simply rocks.

Two weeks ago i bought a Siemens Gigaset E494IP and wanted to hook it
up to the sip-server of the Fritz-Box through the local LAN, but that
didn't work out well : "Provider registration failed" is what i got
when choosing 'Other Provider' as VoIP profile. In contrast the Twinkle
soft-phone using the sip protocol works right out of the box with the FB
7340 :

To be honest i have some strange feelings about these Siemens Gigaset
IP Phones as it made not even a single attempt to connect to port 5060
of the Fritz.box. See also :

So instead of taking down manufacturers of good hardware like AVM, why
not confront big telco corporations like Siemens with the strange
behavior of their IP telephones ?
