Frequently asked questions

We hope these would be of help

Do Overseas texts cost more?

When you send a text or SMS to another country, the cost depends on whether the phone you are sending messages to, is in another country roaming, or if it originates from the country being texted. There is no extra charge to send a text message to a phone that is roaming in another country, but if the SIM originates in another country charges will apply. Messages are charged per network / destination, costs may vary on messages sent internationally.

Can I use my own Sender ID for SMS?

You can request your required Sender ID through your assigned Account Manager. DMC Telecom recommends using the already existing optimized sender IDs, which are pre-registered for each market. This ensures that your verification SMS will not be confused as marketing or spam with carriers across the globe and reach your users without fail.

Can you use pre-recorded audio for voice calls?

Yes, you can use pre-recorded audio in multiple formats, including WAV and MP3.Pre-recorded messages can be used on a IVR scenario, when you want to play messages in a menu scenario instead of using TTS, and it can also be used on a callout scenario, when the customer want to trigger a call to a destination number, and play a message directly, such as a PIN code for a OTP (One Time Password) call.

Can I use my own CLI (Calling Line Identifier)?

Calling Line Identifiers (CLI) can be used in conjunction with a purchased DID (Direct Inward Dialing service). If we do not have a DID in your region, then we can acquire one for you.

Are there limits to number of messages sent using Zalo OA?

Messaging limits determine how many users your business can send messages to on a daily basis. This includes new conversations as well as existing conversations with users. The messaging limit does NOT limit the number of messages your business can send, just the number of users you are trying to send messages to. It also does NOT apply to messages sent in response to a user-initiated message within a 24-hour period.

What is a Flash Call Verification?

This allows numbers to be verified without any user interaction at all or for web application verification with minimal user interaction. It works by placing a dropped call to the recipient where the incoming call number is the OTP code, equivalent to the OTP code in an SMS. The code can be processed automatically on Android for a seamless user experience. It is recommended that you do not rely solely on flash call verification and that you should try flash call first and if flash call fails you can automatically fall back to SMS or you can allow the end-user to start SMS-fallback.
