CRM Integration

To be able to use the integration specific functions, each user using the CTI needs to have the CRM Integration additional service‍ on their hallo, user. This can be added in the admin portal by an administrator.

Hard refresh

If you’re having issues with the CTI please do a hard refresh in your browser and clear your cookies/cache. This can resolve multiple problems which may occur. The primarily recommended browser for our app is Google Chrome (or other chromium-based browsers).

To do a hard refresh in Chrome for windows it is CTRL + F5  and for MacOS it is CMD + Shift + R. Manually clearing cache and cookies in your browser settings can also sometimes make an impact, even if you’ve already made a hard refresh.

Gigaset C530 consists of a handset (on the left side of the picture), and a base station (on the right side of the picture). 

Make sure that the power cable is connected to the base station from the back side of it, and the network cable is connected to it from the side.

Factory reset base station

The base station:

1. Disconnect the power and network cables.
2. Hold the button from the front side of the base station.
3. Connect the power cable back to the base station.
4. Release the button on the front side of the base station when it starts to blink blue.
5. Connect network cable.

If you have successfully done the factory reset, the handset is automatically disconnected from the base station. If this has not happened, repeat the steps above for the factory reset.

Reconnect the handset to the base station

1. Go to settings (cogwheel) in the handset.
2. Register.
3. Register handset.
4. Press the button on the front side of the base station until the handset is registered.
5. In case the PIN is asked, type in the PIN: 0000.

To check which handsets are connected to a base station, you can press the button on the front side of the base station, then the handsets which are connected to the base station, will start ringing.

Factory reset handset

1. Go to settings(cogwheel) in the handset.
2. System.
3.  Restore handset.

Then follow the instructions above to connect the handset back to the base station.

Network

Another network cable/output

Make sure that the base station really is connected to a network with the network cable. Connect the base station with a network cable/output you know that is working, for example one from a computer or another functioning telephone.

Another network

Test your Gigaset in a completely different network. If possible, you can take it home to test it in your home network. If there seems to be an issue with the phone only in a specific network, the firewall settings need to be changed in that network. You can change the settings yourself or ask help from your network provider. You can check the settings from this article‍.

Contact hallo,

In case you cannot set up your Gigaset, contact us and we can have a look if something looks wrong behind the scenes or if we have some tips on how to proceed.

Make sure to inform us what the problem is, which number is connected to the Gigaset, as well as the MAC address which you can find under the base station. With the help of the MAC address, we can see which entity you are trying to set up.

If you are contacting us by email, please take a picture of the MAC address under the base station and attach it to your mail. This is reducing the risk of the MAC address being read wrong.

Create a rule for all UDP and TCP ports for hallo,  networks 80.83.208.0/20.

For this rule, there should be a Timeout (TTL) of at least 3720 seconds, as our phones contact us every 3600 seconds. If you can not increase your TTL, contact our support and we can reduce the registration interval on the phones to 120 seconds.

For incoming traffic:

No rules are needed here because the session is initiated from within the network. Disable all ALG / SIP functions and Application Control on the traffic to hallo, if this is in the firewall. These usually do more harm than good.

Complete information about our network:

Address: 80.83.208.0

Netmask: 255.255.240.0 = 20

Wildcard: 0.0.15.255

Network: 80.83.208.0/20

Broadcast: 80.83.223.255

HostMin: 80.83.208.1

HostMax: 80.83.223.254

Hosts / Net: 4094

If you bought a Gigaset phone from us, you also need to open up traffic to their server so that they can retrieve their settings correctly. The addresses of these are:

Gigaset 148.251.91.32 – 148.251.91.63 (148.251.91.32/27)

148.251.246.96 – 148.251.246.127 (148.251.246.96/27)

148.251.243.128 – 148.251.243.159 (148.251.243.128/27)

Protocol

Below are the protocols used by equipment supplied by hallo, as well as a description of their function. Different terminal types use different protocols, e.g. HTTPS is preferred for downloading software over e.g. TFTP and HTTP, but in cases where the terminal does not support HTTPS, one of the others is used. hallo, does not recommend blocking traffic to and from terminals based on ports and / or protocols, but rather chooses to trust all traffic to and from hallo, networks. hallo, also does not undertake to use only the protocols below for the future, so a restriction of permitted traffic through firewalls based on the following risks affecting delivered services in the event that the specification below changes. Note that the ports listed in all cases are receiver ports, as a rule rather than exceptions, the equipment uses randomly selected sender ports.

FTP
File Transfer Protocol, RFC959, TCP ports 21 and 20. Used to download terminal configuration and software.

DNS
Domain Name Server, RFC1035, TCP / UDP port 53. DNS functionality is part of a working IP network and the terminals provided by hallo, will not work unless they have access to a working DNS. In the case where the DNS is located outside the firewall, the firewall must allow the terminals to look it up.

Our provisioned phones are configured with Google’s DNS 8.8.8.8 and 8.8.4.4

HTTP
Hyper Text Transfer Protocol, RFC2616, TCP port 80. Used to download terminal configuration and software. No specific configuration is normally required for HTTP to work satisfactorily as this is one of the most commonly used protocols on the Internet.

HTTPS
Hyper Text Transfer Protocol over Secure Socket Layer, RFC2818, TCP port 443. Used to download terminal configuration and software.

TFTP
Trivial File Transfer Protocol, RFC1350, UDP port 69 and dynamically allocated ports for data transfer. Used to download terminal configuration and software.

SNTP / NTP
Simple Network Time Protocol, RFC1305 / RFC1361, UDP port 123. Used to set the time / clock in the terminal.

SIP
Session Initiation Protocol, RFC3261, UDP port 5060. Used to hook up and down calls. SIP traffic runs between our SIP server and the phone. This is by far the most important protocol for your telephony to work.

RTP
Real Time Transfer Protocol, RFC1889, UDP port 1024-65535 (hallo,  uses UDP port 10,000-20,000). The audio stream between the terminal and the phone during a call flows as RTP. The port used is randomized when a call is initiated. All terminals supplied by hallo, use symmetrical RTP, which means that the receiver and sender port for the RTP stream are the same for both incoming and outgoing audio stream. This means that the audio stream that goes from the terminal to us opens the session in the firewall to also allow incoming voice stream over the same session.

SRTP
Secure Real-Time Transfer Protocol. Still transported over UDP but both parties of the call have exchanged keys during the connection of the call in the SIP dialogue to enable encryption.

RTCP
Real Time Control Protocol, RFC3550, UDP port 1024-65535. Some terminals generate RTCP packets that are used in the communication between RTP endpoints to convey local statistics and call data such as information about jitter and any packet losses. This is selected as the RTP port + 1, ie. if the RTP stream passes port 12480, RTCP will use UDP port 12481.

WSS web socket
WSS used by our softphone “hallo, desktop” and uses port 8443 against “push servers” and port 443 for SIP.
