Configuration Detail

• Start Zoiper IAX SIP VOIP Softphone App.

• On the welcome screen fill the Username and Password then click on Create an account.

• • Username: 100000 (your VoIP.ms main or sub account) @server.voip.ms is optional.
  • Password: ********* (account password)
    

• On the host screen fill the domain/host with any of our servers. I.E. toronto.voip.ms then click on Next

• Skip the Authentication step. AuthUserID and Outbound Proxy are not needed.

• In this screen you can select the protocol that your SIP account will use:
  • SIP TCP
  • SIP UDP
  • IAX UDP

Select the one you prefer according to your network's settings, I.E. SIP TCP then click on the Finish button.

Please notice that we do not support SIP TLS.

Done at this point your VoIP.ms SIP account should be shown under Accounts section and marked on Green with a tick arrow next to it. This means your softphone is ready to start placing calls.

Audio codecs

In order to use only the supported codecs by VoIP.ms please go to Settings>> Accounts>> Your account

Scroll down to Audio Codec Settings., and just enable "uLaw" and "GSM". You can touch over the codec and move it to the top of the list in order to change the order. We suggest keeping "uLaw" at the top. In case, you have bought "g729" make this your first option and move it right to the top.

Network settings

In order to have your softphone running all the time, proceed with the following steps:

1. Go to Settings>> Connectivity and enable "Keep Alive WIFI" and "Run in Background"

2. Go to Settings>> Accounts>> Your Account>> Network Settings and change "Registration Expiry Time" to 180

Common Errors

No transport mode found

• If there was a typo in your password or if there's a DNS issue Zoiper might show the account type options in red. You can select the protocol and hit the Finish button even though they're all red.

Note: Sometimes even when the username, password and server's name were typed fine, Zoiper will show all those options as "Not found". However, you can choose your desired selection and finish.

SIP error codes

In case your account has been marked on red an error code number will be shown at Settings>> Accounts section. You can check the error response code and correct it. You can check the list of common SIP Response codes for this.

• For best results, it is recommended to use wifi. But if using 4G/LTE and you experience poor sound quality, it has been reported that turning off ECHO CANCELLATION helps solve the issue.

408 error

On some networks, you might get this error code that could disappear when you change to a different network. This could be due to some limitation on the local SIP ports for this network. As a workaround, you can try the following modifications to your settings.

1. Go to Settings>> Conectivity>> Listening Ports and untick "Random Port" for Local SIP port only and type 5080 in the port field.

2. Go to Settings>> Accounts>> Your account and at "Host" add :5080 to the server's name.

Zoiper PUSH service

If you're experiencing issues with outgoing calls using the new Zoiper's PUSH server. Please follow these steps:

1. At Settings >> Connectivity:

• Check/Enable the "Enable PUSH Proxy" option.
• Set "Proxy protocols" to SIP+RTP.
• Set "Push transport" to TCP (Default).

2. At Settings >> Accounts >> Your account

• Set "Authentication user" with your Main or sub account name. (It's the same value you have for "Username")

3. At Settings>> Accounts>> Your account >> Network settings

• Set "Transport Type" to TCP
