MMS Integration

[pbomboy]

I purchased services from Telnyn, and SMS works great, but MMS does not work. Images sent to 3Cx Chat are not being received on the MMS Number. How ever I can sent attachments from 3cx web client to the external carrier MMS and they are received. Telnyx reports this is a 3Cx issue, and confirmed the content of the picture sent.
V18

Hi @pbomboy,

If you log into your Telnyx portal, under routing does your Deliverability show that MMS is enabled?

Hi @pbomboy,

If you navigate to your Management Console >> Messaging >> MMS: You'll see the link to copy that should look something like: https://messaging.3cx.com/v3/webhook/XXXX-XXXX-XXXX-XXXX/etc.

After updating you should see link displaying /v3/webhook/... Copy that link and log into your Telnyx account, check that it is not v1, it should be v3.

Yes it has v3

At telnyx it was listed as V2. Now I can receive pictures, I still cannot sent them.

Hi @pbomboy,

Where are you trying to send from? (which 3CX Application?)

 

[pbomboy]

I believe this may be due to file size. The original picture is 3MB. I can send a small jpeg 202KB

Hi @pbomboy,

Where are you trying to send from? (which 3CX Application?)

Android V 16.7.8.121

Hi @pbomboy,

Are you able to send MMSes from any other 3CX application?

I downloaded the image from android photo gallery, and attached it through the web client, that worked.

I downloaded the image from android photo gallery to a windows pc, and attached it through the web client, that worked.

I can also see all the photos that were sent via android are present in the Web client. Must be a bug with android. I will try IOS later.

Interestingly enough. If I open the web client on the android device and take a picture, it will not send. I have also tried to attach a stored camera image .jpg is also does not sent from the web client on android.

Hi @pbomboy,

Here is a good read: https://support.telnyx.com/en/articles/3102823-mms-sending-and-receiving

Summarising: If you send anything over 300kb, Telnyx can't guarantee that it'll make it to the destination (it depends on the destination provider as well).

Hi @pbomboy,

Are the MMSs you're sending under 300kb in size?

 

[pbomboy]

Hi @pbomboy,

Are the MMSs you're sending under 300kb in size?

Via android - No. Using the web client I am able to send a 2.5MB file.

 

[pbomboy]

I just resized a photo down to 600K, and it went through.

Via android - No. Using the web client I am able to send a 2.5MB file.

 

[VasilisV_3CX]

Great, glad that we've managed to discover what the problem was @pbomboy.

Note that we're considering adding a feature to prompt you to automatically resize the images prior to sending. It will most certainly appear in the change logs / blog.

 

[pbomboy]

When I get a single picture file to go through it sends the message with 2 pictures

 

[VasilisV_3CX]

Is that from both the Web Client and the Android App?
