The VoIP Gateway 5188 was the attempt to bring (in this time way cheaper) VoIP Telephony to small companies, while providing a fallback to fixed line ISDN Telephony for 8 simultaneous lines. The 5188 was the first model supporting SIP-Trunking and provided a PBX system for up to 24 ISDN telephones.

In this time VoIP was not as reliable as today, that is why this is the only model which offers a VoIP button, to toggle between VoIP and ISDN Telephony. The 5188 also was the first model running 2 intances of FRITZ!OS on 2 SoCs, since a single AR7 did not provide the CPU performance to run the VoIP Codecs for 8 lines.

Initially proposed for 580 Euro the recommended retail price dropped to 495 Euro when it came to the market.

Note that the information above is merged from all current Firmware versions available for this model, if there are multiples.
For a more detailed per Firmware view see the Firmware-Scans below, and have a look at the Firmware-History.

Daily updated index of all VoIP Gateway 5188 firmware modding projects. Last update: 2024-03-03 08:18 GMT.
This list excludes community ripping, code raping, project killing and permanent quarrel and combat enforcing individuals.
BoxMatrix tries to be a service to the community without doing harm to anyone, and not a platform to advertize the opposite.
Mother nature will bill for all time, manpower, projects, fun and passion which was ripped from the community for sick battle.
Let this reaver suck all honest work on this planet and pretend he knew it first. Mother nature will ripp it off his bones.
And if this sick (single sided) perversion continues I have no other option than invoking the police. Please someone stop him.

Daily updated index of all scanned VoIP Gateway 5188 tarballs, most of which are online. Last update: 2024-03-04 05:30 GMT.
The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
The Ver column shows the Firmware-Version derived from the tarball's filename, or 00.00 if not detectable.
There's no way to find this number in the source. Click the version number to get a listing of the entire tarball.
The Kern column shows the Kernel-Version from the kernel Makefile, click it to get a listing of the kernel source.
The BB column shows the BusyBox-Version from various scan sources, click it for listing the busybox addons.
The Libc and LcVer columns show the Libc-Library and its version where it could be detected, which is complicated, no listings yet.
The CC column shows the GCC-Version from its root Makefile, click it for a listing of the gcc source in the tarball.
The BR column shows the Buildroot-Version if detectable, click it for a listing of its source in the GCC tarball.
The Date column shows the date of the newest contained file. By default this list is reverse sorted by this date.
This is no perfect method, since AVM sometimes repackages older tarballs. No better method has been found so far.
