FIXED TELEPHONY

Using MaxiConnect VoIP services requires a few specific technical configurations to ensure a good connection and call quality. Below you will find all the information you need to configure your PBX system or your VoIP-compatible telephone.

1. Basic configuration information

• SIP host (SIP server): sip.phone.maxiconnect.ch
• SIP port: 5060 (UDP)
  

Make sure that port 5060 is open on your network, as it is used for SIP communications.

2. SIP authentication

You will receive the following authentication information when you create your VoIP account with MaxiConnect:

Username: [provided by MaxiConnect]SIP Password: [provided by MaxiConnect

SIP password: [provided by MaxiConnect]

This information must be configured in your PBX or on your VoIP telephone.

3. Supported VoIP codecs

MaxiConnect supports the following codecs to ensure optimum call quality:

PCMA (G.711 A-Law): A codec widely used in Europe, offering sound quality close to standard telephone quality.

PCMU (G.711 µ-Law): This codec is often used in North America and Japan. It also offers audio quality close to that of standard telephone lines.

Make sure that your PBX system or VoIP phone is configured to use these codecs to ensure compatibility with the MaxiConnect network.

4. Network and NAT settings

If you are using a firewall or router, it is essential to configure NAT management correctly to allow good communication with the MaxiConnect VoIP server.

Here are a few tips to avoid problems with connectivity or call quality:

Use transversal NAT (STUN) if necessary.

Make sure that SIP and RTP (audio) packets are not blocked by your firewall.

RTP ports for audio transmission must be open (port ranges are specific to your PBX or device).

5. Security and encryption

MaxiConnect takes the security of your communications very seriously. We recommend the following best practices for securing your VoIP installation:

Use strong SIP passwords to prevent hacking attempts.

If possible, configure your PBX or telephone to support encryption of communications via TLS for SIP and SRTP for audio packets.

6. Troubleshooting

If you encounter difficulties configuring or using your VoIP service with MaxiConnect, here are some common troubleshooting steps:

Unable to register on the SIP server: Check the SIP host, port, and authentication information. Make sure your firewall is not blocking SIP packets.

Call quality problems: Check that the PCMA and PCMU codecs are activated. Check that your network bandwidth is sufficient and that the NAT configuration is correct.
