Currently, we have fax server on premise with multiple modem/analog lines. There are 4 dedicated lines for outbound. So, we can have up to 4 faxes sending simultaneously. Our developer is working on RC fax API to route outbound fax to RC. We don't know how many simultaneous faxes can be sent at one time per line/extension on RC. Do we need to setup a fax group (with multiple line/extension) for outgoing faxes, so the outbound fax can hunt for available line to send without waiting? We fax average 6000 page (patient result) per month to MD office and hospital. We don't want any delay if faxes are sitting in queue and sending out one by one.
Hi, faxes are sent individually to recipients and may take 1 minute per page. You may check these KB Articles to know more about Fax Transmission.

In our scenario, we want to send multiple faxes at the same time to prevent the delay. How can we achieve that with Ring Central Fax API? We have multiple extension from Ring Central. Can we create or add multiple extension to a fax group and send fax to the group?
@Manh Le, I will be moving your posts to our Developers site so they can help you with this.
Thank you Mary.
Basically, every user extension under your account (company) will share the same fax number (which usually is your main company number). Thus, every fax sending out thru the same number will be on the same queue.
For your use case, I suggest that you should add more phone numbers (let's say 3 more plus the current main company number to match your 4 lines). Then you should create 4 dedicated extensions (let's name them "Fax station 1", "Fax station 2" etc.. Each "Fax station" extension will be assigned with a different fax number.
Set Fax settings for each extension
Select Fax number for each extension
Now it's up to you to implement your fax app to select a "Fax Station" extension to send out a fax. You can query fax messages status of each "Fax Station" to see how many faxes are on the queue of that fax station and decide which one you want to use for sending a new fax.
Thank you Phong Vu. Your information and instruction are very helpful. We also need to know if we can customize and use our own fax cover page instead of the built-in cover page from Ring Central. I read an article from RC community about custom cover page from Ring Central App. Not sure we can create and use custom cover page with Fax API. Your help will be greatly appreciated.
Unfortunately, there is no API for creating a custom cover page. You can customize your cover page under the same user's fax settings with cover page info. Or, you can workaround this by creating a cover page dynamically, convert it to pdf or an image and send it as the first page of your fax.
Hi Phong Vu. You are very helpful.
Hi Phong, my understanding is Ring Central line support both voice and fax. Can we receive inbound or make outbound call when sending/receiving fax on the same line? For example, we have extension 110 that configure for both voice and fax. Will the line be busy for voice call when it is sending/receiving fax? Or, voice and fax are functioning independently for each line.
I am not 100% sure but can be 99% sure that a fax line will be busy if there is an active voice call on that line. It's not hard to check and verify such a situation though. Just make a call and send a fax during a call.
Actually, I tested this before I ask you. It seems I can still make or receiving phone call when the fax is sending. We just want to check with you to see if you know about this. Can you find out and confirm this for us? I just test again with extension 110. I can still login to Ring Central phone to make or receive voice call when the fax is sending out on extension 110.
Are you sure that while you are on the call from the same number as the fax number, the fax is in "sending", and NOT in "queue" status? Basically, you can be on a call and start sending a fax, but our system will create the fax and put it in the queue and as soon as the call is disconnected, the line be comes available, then the fax will be sent. Pls double check and let me know. Or if I have some time, I will test this out.
I started the fax first. I see the fax is in queue and sending. It is a 20 pages fax and it take a while to send. During the fax is sending, I test with the call. It works fine for either inbound or outbound call.
Good to know. My knowledge about fax line could be out dated and now it is more advance. I will let you know if I could verify with the engineering team.
