Incorrect Time on SMS

[Tony Roth]

I have a customer that is using a non-certified SIP trunk provider. They have SMS turned on. The only problem they are having is it seems like inbound texts and replies to 3CX phone numbers are using UTC and not the time zone the user is in. The 3cx users responses are in the correct time zone. I saw one previous post about this but no responses. Has anyone run into this?

I would recommend checking this with your SIP trunk provider first to determine whether they are supplying the SMS timestamp and, if so, why it is being sent in UTC.

Since you are using a non-certified SIP trunk provider, we cannot confirm how they format or populate the SMS timestamp. They should be able to advise whether this is expected behaviour or if they can send the timestamp in the appropriate time zone.

I have not contacted them directly since they have a separate login where you can monitor the sms/mms and the time is correct on in that portal.

Have you asked the provider to verify the data they send to 3CX and confirm whether they include a timestamp with the SMS messages?

As this is an unsupported SIP trunk provider, we are unable to investigate or advise on their implementation.

If you can reproduce the same behaviour with a supported and certified SIP trunk provider, please open a support ticket and we will be happy to investigate the issue further.

I just opened a trouble ticket with them to see if they had any information. I understand that it is not a certified provider.
