    Angry Nokia supporting SIP is a fraudulent claim

    I'd like to invite someone from Nokia to explain how they can reasonably claim that their phones are supporting SIP.

    Apart from having a number of correct sounding configuration options in the phone connection settings, no matter what you enter into these the phone is incapable of connecting to all but very few VoIP providers out there.

    I have a WLAN to which both a laptop and a Nokia E65 is connected. On the laptop it took about 30 seconds to install and configure the soft-phone XLite to successfully connect and register with the VoIP provider (i.e. to an Asterisk PBX).

    No matter what I do on the phone all I get is a 401 Unauthorized response, and if you ask Google on this topic you'll find TONS of other people with similar problems and very few reports of success. Even in this forum there are a lot of complaints and no-one from Nokia seems to be able to step in and provide answers or explanations.

    There is no end to how mad this makes me - I bought the E65 to get a combined cell/sip phone, but in practice it's nothing more than a regular cell phone. In my book that is fraudulent and misleading, and unless something drastic happens to the (lack of) built-in SIP functionality soon I'm sending back what could otherwise have been a great phone and permanently switching to something else.

    Re: Nokia supporting SIP is a fraudulent claim

    The phones do support SIP, however they are a little "pickier" about how things work than many SIP implementations are. This means it won't work with every SIP server out there out of the box. I was able to get an Asterisk system working with other S60 3rd Edition devices with a very specific configuration. Also, Gizmo Project and Truphone are both SIP-based services and they work with the devices.

    @mnmr
    I agree with you
    I must use fring client freeware on my E65 and it's a very good software
    who can connect my Asterisk IPBX each time, but it's not normal to use a third party software for that. fring have just a problem I can't send DTMF code and check my voice mailbox.

    Nokia have to update the firmware for SIP client that's all !!

    Re: Nokia supporting SIP is a fraudulent claim

    I also stated above that I was able to find sporadic success reports. However, Nokia has been very unforthcoming in explaining why their SIP implementation is so sorely lacking compared to other implementations (see other topics in this forum).

    Also, despite numerous problems with users having problems with 401 (Unauthorized) responses from Asterisk there have been no answers or solutions from Nokia as to where the problem lies or what one can do to remedy it.

    A SIP implementation that only works with 2% of the voice IP providers shouldn't be called a SIP implementation. It's like advertising a lamp that can display all colors, but after you buy it you discover that the on-off button only works for red. The lamp may be able to emit other colors, but only if you use a special brand of light bulbs. It's just not what you expect when you buy a piece of equipment with an advertised standards-based feature set.

    CORRECTION: Truphone only work with one plug-in.
    For now I use Fring. The bad side is the great batterie consuming.

    yes fring is consuming batteries but it's a good software.
    So now problem with Nokia client is solved just fill domain with asterisk
    and it's ok. I have bought recently Gigaset C455IP and it's the same way
    to registering realm is asterisk.
    In fact Gigaset for home or facilities using is best choice.
    DECT very powerfull and long range, can use repeater, can have 6 sip account by base for six phone.
    Nokia wifi have very bad range and very fare of gigaset feature.

    Re: Nokia supporting SIP is a fraudulent claim

    As mnmr says, Asterisk is sending 401 and asking
    that way for Digest authentication.
    The reason for SIP registration failure
    in this and most other cases are invalid or incomplete SIP settings.

    E65 and other current S60 based phones require that
    you to configure the registrar's Realm in SIP settings before trying to register.
    This is a limitation that most PC VoIP clients do not have
    and the value of Realm is not even visible in their settings.

    You need to figure out which value Asterisk uses
    in the realm-field of the 401 SIP response.
    This is of course usually too tricky for a basic user,
    if the operator of the registrar does not provide this information.

    If you manage to get this information,
    you need to fill the following fields in SIP settings
    according to your user account for Asterisk:
    Registrar server -> Registrar address, Realm, Username and Password.
    As said, it is essential that the value of Realm-field
    is exactly as configured to your Asterisk server.

    For Asterisk, you could just try value "asterisk" for Realm.
    It might just work...
