The server will check for updates every 30 minutes. The phone will only display the contents of the 'title' tag of the first 'entry'.Known problems
- No support for MWI on VoIP channels, see comments. fixed with latest firmware
- If the sip.conf section for the S675 IP contains a 'voicemail=<mailbox>' statement, asterisk will complain about '415 Unsupported Media Type' each time asterisk tries to tell the phone about the voicemail status. As PieterB pointed out, asterisk actually ignores the list of accepted applications sent by the phone. fixed with latest firmware
- The RSS feed only displays the title of the first entry in the feed, and it does not seem to accept all common feeds.
- Menu 8-5-1 (Call List Type: Missed calls/All calls) is missing.
- Workaround: To activate "All calls", press Menu (right arrow), enter 8 5 then 910, display shows: 910 SET (0), enter 1, press OK to activate.

Notice: You will hardly find a power adapter for this phone, not because the 6.5V power switch is difficult to be found but the adapter that switches to the phone is not a standard one. You have to cut the cord and you loose the guarantee.

Re: Jabber Account per handset?
The same goes for email check. (it should be one pr handset !)
MWI Problem
Das Gigaset S675IP akzeptiert (RFC-konform) nur SIP-Notify Messages die auch vorher via Subscribe-Message angefordert wurden.
Die meisten übrigen SIP-Telefone am Markt akzeptieren jede (auch nicht-subscribte) Messages. Asterisk unterstützt erst ab Version 1.4 SIP MWI-Subscriptions.
Prüfen Sie bitte, ob Sie eine Asterisk Version > 1.4 nutzen.
In english it means that the S675IP only take SIP-Notify Messages wich are requested before. Asterisk > 1.4 uses the SIP MWI-Subscriptions.
I hope this information helps.

Problem MWI with Firmware version: 020970000000 / 041.00; EEPROM version: 114 not resolved
Message waiting indicator still doesn't work on voip with firmware version 02097 (12/2007).
S675IP doesn't fully compatible with rfc3265 MWI (http://www.ietf.org/rfc/rfc3265.txt),
The error is:
-- Got SIP response 481 "Call Leg/Transaction Does Not Exist" back from <IP>
Works on asterisk PBX (version 1.2.25 and 1.4.17), but without MWI. It is a big problem for me.
Waiting for a new firmware, and hope it include MWI bugfix ...
P.S : have same problem whit a c470ip (same firmware)
Ludo.
call disconnects every 30-32 minutes from SIP server
The same happens with a C430 IP
Any idea?
Problem fixed: I disabled all communication services, Gigaset.net, e-mail checking, etc and now everything is fixed. My e-mail was checked every 30 minutes and probably this caused the problem, my full mailbox probably. You can add it as bug probably!
MWI still not working for me
Yes, they added the possibility to check voicemail on other servers, not just on the one in the base station (that I have never and will never use), but at least my Asterisk will give me other errors when I try to use it. Have you had better luck, please let me know, and tell me how.
Add: The error is:
-- Got SIP response 481 "Call Leg/Transaction Does Not Exist" back from <IP>
I just left a message for myself, my Linksys SPA941 lights up right away, the Siemens S675IP still has no clue about any messages waiting.
I am just waiting for the day when I can buy a Snom M3 (or a few of them) and ditch this Siemens crap.
Re: 415 Unsupported Media Type
Re: 415 Unsupported Media Type
As this phone is the only one to exhibit this MWI problem, i think that Siemens should correct this asap, Asterisk is a defacto standard now. Siemens is making users unhappy trying to use special methods in their firmwares.
MWI does not work with Asterisk
This phone seems to have the same problem as the C470IP do have.
The message waiting indicator does not work. In rare occasions it is possible to get the MWI lamp flashing. Most of the time it is after the base has been rebooted. After a first message indication it will not work again for subsequent messages.
I would have expected a better tested hardware from Siemens. I ask myself if they are producing IP phones to earn money or only to write their Name on the phone body.
We had some big missing functionalities with the C450IP (no IP call transfer for example), this has never been corrected. I hope that the C470IP / S675IP firmware will receive more attention from Siemens.
Hopefully we have now other serious DECT SIP manufacturers.
Jabber Account per handset?
Can someone with either set of phones confirm this either way, I'll even setup some accounts for you to test it if you need that!! :)
Cheers,
Mark
Re: 415 Unsupported Media Type
In sip.conf, comment out or remove the mailbox= statement:
;mailbox=42
Then asterisk will not try to tell the phone any voicemail status. I wish there was a more elegant and functional solution, but it will have to do for now.
