The All-IP Voice SIP Trunk from O2 was first tested and released with SwyxWare 188.8.131.52.
The All-IP Voice SIP Trunk from O2 is a SIP Trunk with user authentication, i.e. you receive information on user ID, user name and password. The names may differ, or you may only receive a name or ID with password. In this case the user ID is identical to the user name when configuring the SIP trunk in SwyxWare.
The connection to the All-IP Voice SIP Trunk from O2 can only be made via an Internet connection from O2. For this purpose, the customer receives an Internet router that is integrated into the customer's network (OneAccess Gateway). SwyxWare uses this Internet router as a SIP proxy to connect to the All-IP Voice SIP Trunk from O2. The Internet router provides the Internet connection (data line) via Ethernet ports 0/2 and 03, the voice connection is provided via Ethernet ports 0/0 and 0/1. Additional information can be found in the attached document from O2 (in German only).
If the SwyxWare server has to use both connections, it needs a second network card.
The All-IP Voice SIP Trunk from O2 can be used from SwyxWare 184.108.40.206 on. When using an earlier version of SwyxWare incompatibilities cannot be excluded and use is at your own risk.
The All-IP Voice SIP Trunk from O2 is not suitable for central connection in the data center.
The SwyxWare Server is equipped with two network cards.
- Network card 1: Data, connected to OneAccessPorts 0/2 or 0/3.
IP-Address, Subnetmask, Default-Gateway, DNS Server according to the ordinary data network or via DHCP respectively.
- Network card 2: Voice, connected to OneAccessPorts 0/0 or 0/1.
- IP-Addresse from the Voice network of the OneAccess Gateway, e.g. 192.168.222.2
- Subnetmask: 255.255.255.248
- GW: empty
- DNS: empty
The LinkManager must use network card 2 for the voice connections. A new registration key must be created for this purpose:
- Path: HKLM\Software\Wow6432Node\Swyx\LinkManager\CurrentVersion\Options.
- Name: SipLocalInterface
- Type: REG_SZ
- Value: The assigned IP address of network card 2, e.g. 192.168.222.2
When creating the SIP trunk group, select the profile 'O2 All-IP Voice SIP (DE)'.
- Path (64-bit): HKLM\Software\Wow6432Node\Swyx\LinkMgr\CurrentVersion\Options
- Name1: SipMinSessionTimerIntervalSeconds
- Type1: DWORD
- Value1: 1800 (decimal)
- Name2: SipSessionTimerIntervalSeconds
- Type2: DWORD
- Value: 1800 (decimal)
- Incoming/outgoing national /international calls
- Correct Calling Line Identification (CLI) on national / intenational calls
- CLIP No Screening national
- Holding and retrieving calls
- Toggeling between two calls
- Call transfer
- Call forwarding
- Mutually supported codecs: G.711a/ G.711u/ G.729
- Incoming/outgoing DTMF signaling in accordance with via RFC2833
- FAX transmission via T.38/G.711

Verifying interoperability between different SIP providers and the Swyx solution is part of the Enreach Technology Alliance Programme (TAP) tasks. Due to different implementations of the SIP RFCs, it is necessary to determine and provide an individual configuration for each SIP provider.
Within the TAP, Enreach tests a large number of national and international SIP providers in order to make statements about the interoperability with the Swyx solution and the functional scope of the respective SIP trunk. These results and, if needed, configuration advice are published in Help Center articles.
Enreach is in close contact with selected SIP providers to ensure a quick troubleshooting in case of incompatibilities. In addition, tests are repeated at regular intervals to ensure consistent quality.
Despite regular retests it cannot be excluded that incompatibilities with the Swyx solution may occur due to changes in the SIP connection on the provider side or that the provided profile is no longer valid. After creating the trunk group or SIP trunk, the profile settings should be compared with the provider's information and adjusted accordingly in case of deviations.
However, should incompatibilities or problems occur with a tested SIP trunk, no claims for recourse against Enreach GmbH can be derived from this. In such cases, you can contact Enreach Support via your specialist dealer.
