FAQ

Here is the list of our SIP gateways:

We recommend allowing traffic based on DNS names rather than static IP addresses to ensure reliability.

Please note that media IPs (unlike static SIP signaling IPs) are numerous and change frequently, you should allow RTP audio on ports 10000-20000 from ANY IP in your firewall.

API access is available for Plus account level and above. If you are currently on a Core plan, you will need to upgrade first. Once the upgrade is completed, please contact your account manager to request your API key.

You can review and download your call history by logging into your didlogic account and going to the History tab. From there, you can export the list of calls.

A missed call is an inbound call to your DID number that was not answered by your endpoint PBX.

Yes, you can request a downgrade to a lower account level.

If you have already selected a lower level, the downgrade will take effect at the start of the next billing cycle, after all obligations of the current plan are fulfilled. Charges for the current billing period still apply.

In special cases, a refund or adjustment may be considered, subject to internal review and approval. We recommend contacting your Account Manager for assistance.

To close your didlogic user account, please email [email protected] or open a ticket from the “Support“ tab on your didlogic user portal, clearly stating that you wish to have the account closed.

The monthly commitment fee is the minimum monthly spend required for the selected account level. If the actual usage does not reach this amount, the difference is charged as a commitment fee.

Please note that, according to the ToS, the commitment fee cannot be disabled while the account is active.

To learn more about the available account levels, please follow the link.

You were charged as part of the monthly commitment fee associated with your selected account level. This amount is automatically applied to your account from the date your account level was activated.

The per-minute rate for inbound calls forwarded to a PSTN number depends on the destination country and the type of number to which the call is forwarded.

You can view the applicable rate directly in the portal by following these steps:

Log in to your didlogic account and go to the Purchased tab.

Select the DID and, in the Forward to dropdown, select Phone. Then, enter the destination number in E.164 format (country code followed by the number).

Click Add.

Once the PSTN number is added, the inbound forwarding rate for that PSTN destination will be displayed next to the added number.

Yes, there is a solution. Please contact [email protected], and we will share the list of IP addresses that should be allow-listed.

To enable TLS, configure your endpoint to use the TLS transport method.

For PBXes, download the root certificate (ISRG Root X1) from https://letsencrypt.org/certificates/ and add it to the trusted certificates on your device.

Once configured, our system will automatically respond using TLS.
didlogic supports TLS on port 5061.

For SRTP setup on inbound calls, please contact [email protected]

didlogic supports the following DTMF methods:

In-band – DTMF tones are transmitted directly within the voice (audio) channel.

RFC2833 / RFC4733 (RTP events) – DTMF signals are transmitted separately from the voice stream as RTP events.

You can increase outbound channels up to 20 directly. CPS is not increased on Basic accounts.

Higher limits are available after enabling required security measures, such as 2FA and IP restriction on SIP accounts.

For limits above the standard thresholds, please contact your Account Manager for approval.

The document requirements vary depending on the direction, type of number, and option. You can select the appropriate number on our portal, and in the requirements section for the number, you will find the necessary documents.

Profile validation takes place within 24 hours after account creation. Our compliance department will review and confirm your account.

Not all numbers are available for self-purchase. However, that does not mean we do not offer them. If you are unable to find the numbers you are interested in on our portal, please feel free to contact our Provisioning Team.

The list of available countries can be found on the website. In the “Buy” section, the desired direction and corresponding prices are available.

As per UAE and KSA local Telco regulation rules, the international caller IDs should be allowlisted first to ensure proper call behaviour. The requirements for allowlisting are as follows:

1. The number that is used as the Caller ID should be a valid and available for callback.

2. The call to the number should be answered by a live person or a valid IVR that will be followed by connecting to the live person.

Once you ensure the number meets the requirements above, please contact the Support Team at [email protected] or via the didlogic Portal with the allowlisting request.

The number porting may be rejected for various reasons at different stages of the porting process. Our LNP team always submits an email outlining the reason for the rejection. If you have not received this email for any reason, please feel free to contact the LNP team ([email protected]) for clarification.

Please be informed that didlogic does not guarantee the numbers will work with WhatsApp.As per the Terms and Services of WhatsApp, a VoIP number is considered unsupported.
