SMS via SIP service is only available through SIP Protocol and user/password authentication. IP Auth and IAX2 are not available at this time.

Please refer to our guide SIP/SMS with FreePBX for instructions on how to configure the service with a FreePBX

Sending

DID must have the "Short Message Service (SMS)" service option enabled. This option can be enabled from the Manage DIDs > Edit DID page.

To send an SMS from your SIP account, it is required that you set your Caller ID number to one of your SMS enabled DIDs. This will be the number you will be sending the message from. You can configure the Caller ID number from your customer portal for the specific subaccount if you are using a softphone or directly from your extension or trunk if you are using an Asterisk or PBX server.

It's important to note that if you configure your caller ID name in your SIP client to be a 10 digits number, this will override your caller ID number. If the caller ID name is anything different than a 10 digits number this will be discarded and the Caller ID number will be used.

If you are an asterisk or PBX user, please make sure to use the latest version of Asterisk (v12 or higher) and use chan_pjsip for the trunk. This is an asterisk limitation.

The Desktop version of Zoiper requires the user to have the PRO version activated to be able to send SMS messages as well as to enable SIP Presence. Please contact Technical Support to request SIP presence to be enabled for your account for the VoIP.ms POP you are using. While normally not required, there may be other cases not documented of softphones or apps requiring SIP Presence to be enabled. Please contact technical support if you encounter any issue with your specific software.

The free Desktop version of Zoiper cannot send SMS messages and is only capable of receiving SMS.

The mobile version of Zoiper is completely free of these limitations. Free version already works for sending and receiving without the need of SIP presence.

When sending an SMS message, the recipient number must be 10 digits. Avoid using the prefix '"1"' since is not supported at the moment. The system will recognize the numbers as in 10 digits.

The current characters limit for a single SMS is 160. If a message is bigger than 160 characters it will be split into blocks of up to 160 characters each and be sent as independent messages. The maximum total message length for SMS via SIP is 2000 characters.

Receiving

DID must have the "Short Message Service (SMS)" service option enabled. This option can be enabled from the Manage DIDs > Edit DID page.

Enable the option "SMS SIP Account" and select the account destination for your SMS messages to this number.

The account receiving SMS must be registered successfully in any of our POPs.

To ensure the best results receiving the SMS messages, do not register the same SIP account on more than one softphone or app at the same time, this can lead to unexpected results.

For SIP devices that require this information, such as a trunk or PBX, we encode the original destination number in a custom SIP header field named "X-SMS-To".

3CX softphone currently does not support any third party SMS service. It will only work by having a direct connection to the 3CX PBX system. Please contact 3CX for more details.
