New Inbound MMS / Active Conversation

[mastervisiontec]

Hello,
Having a specific issue where if a client sends an MMS to our DID, the message will not be delivered to 3CX. If we try to send a client a text that previously sent an MMS to us first then we will get the "Number already has an active conversation with extension". The only way to resolve this is to clear and purge chat history.

3CX is up to date., Telynx (V2) is being used for SMS/MMS. We have no other issues inbound or outbound. This is the only issue that occurs and causes the problem. New inbound MMS will cause all text inbound/outbound to that number to show " Number already has an active conversation".

We have experienced a similar issue recently. Typically appears to be MMS messages that were received by Telco (Telnyx) and was sent to the 3cx webhook but the message is not in 3cx logs. Same environment on our end as well 3cx up to date, Telnyx V2 is being used for SMS/MMS via the trunk routed to a Call Queue. Will update this on my end once I know more about why but want to follow this post as well.

Thanks for the reply @phillytky . What are your thoughts? Do you think it's an issue with Telynx or something on the 3cx side?

Telnyx received the MMS every time this occurred to us. The debug webhook log proves that; but that is all I know. It is on my list to troubleshoot but such a intermitted issue I don't have a large enough sample size to narrow down the problem. The issue is either a problem with the way Telnyx sends the webhook payload to 3cx or it is 3cx having some type of timeout issue. So tbh it could also be Azure VMs as well. Will update when I know more...
