If you’re running into an error while sending messages, it might be because your shared phone pool contains phone numbers that support SMS but aren’t capable of sending multimedia messages (MMS). When you send a message through a phone pool, the system automatically picks an origination number that can handle the message type and destination. If the pool doesn’t have any numbers configured to send MMS, you’ll run into issues.
Here’s what you should check and do to fix this problem:
First, make sure that the phone numbers in your shared pool are MMS-enabled. Not all numbers can handle multimedia messages, and you need to verify that the numbers you’re using are set up for MMS in addition to SMS.
Next, review your pool configuration. When you add a number to your pool, its settings need to match what your pool supports. If your pool was set up primarily for SMS, or if MMS-enabled numbers weren’t correctly added, the system might not recognize any numbers capable of sending MMS.
Also, confirm that the origination numbers in your pool are correctly configured for the message type you want to send. The system filters available numbers to ensure they match the message you’re trying to deliver, so proper setup is vital.
To resolve the issue, start by checking that the numbers in your pool are MMS-capable. Then, ensure these numbers are correctly configured within your pool settings. Finally, verify that the numbers support the specific message type you’re sending—whether it’s SMS or MMS.
Your shared pool can support multiple message types, but only if the right numbers, with the proper capabilities, are present and properly set up. This way, the messaging service can select the appropriate origination identity for each message.
