CLI Phone Port (RJ11) Support for Voice Calls on Arcadyan AW1000 Router

Feature Requests
1

I am currently using the Arcadyan AW1000 router, but I have noticed that the CLI phone port (RJ11) does not seem to function at all. I attempted to check the modem's compatibility and features using AT commands, and the results suggest that the modem is capable of supporting voice calls. Below are the details:

Router:Arcadyan AW1000
Modem Type:Quectel RG500Q-EA

AT+CLCC=?
OK

AT+CREG?
+CREG: 2,1,"E2F9","0683203",7
OK
  
AT+QAUDCFG=?
+QAUDCFG: "slic/AudLoop",(0,1)  
+QAUDCFG: "slic/LF_Ring",(0,1)  
+QAUDCFG: "slic_IndRep",(0,1)  
+QAUDCFG: "slic_cid",<num>  
+QAUDCFG: "pcmidx",(1,2)  
+QAUDCFG: "aif",(0,1),(1,2)  
+QAUDCFG: "i2s/cfg",(0,1),(0-2)  
+QAUDCFG: "uac_cfg",(1,2)  
+QAUDCFG: "uac_switch",(0,1)  
OK

Additionally, I was able to successfully make a voice call using the following AT commands:

ATD; (to dial a number)
ATA (to answer a call)
ATH (to hang up a call)

This confirms that the modem itself supports voice calling functionality.
Would it be possible to include support for voice calls via the RJ11 port in future OpenWrt updates for this router model? This would be a highly beneficial feature, enabling users to fully utilize the router’s hardware capabilities.Thank you for your time and consideration.

have you tried to plug in a phone in to see what happens?

You could just set up sip or voip with some sort of usb audio adaptor.

I have a tplink x80-5g that has an analogue phone port also with a quectel rg500 modem and wondered the same question.

I don't not know how it converts from the analogue port to the modem I'm guessing it has some sort of inbuilt ATA to convert dtmf tone dialing?
I also wonder what demodulates and modulates the voice from the modem to the ata port.

Yes. I checked with 2 different cli phones but not seem to be working. Not even a sound.

There is very little driver support for FXS ports and the chips behind them, so far I'm only aware of chan_lantiq as an asterisk plugin (as part of some, but not all (notable absence, all the AVM ones), lantiq vr9 devices). But this example also shows the main problem with making this a default feature of any kind, asterisk is supported, but it's large and very complex to configure (as well as a high-risk software, in need of constant updating and very close config/ log auditing).

Summarizing:

  • we (mostly) don't have drivers
  • we don't have 'easy', small and secure pbx/ ATA/ FXS suites
  • there is no DECT support at all

All of these things 'may' change in the future, if there were motivated developers (as in, $you) working on this, but realistically I wouldn't bet yesterday's lunch leftovers on it.

So the FXS/ ATA device hangs off a USB port and the modem is configured with usb audio mode and there is a driver/ pbx stack shoved in the mix somewhere?

So I should be able to probe the USB to see the info about the phone adaptor chip then.

No, neither.

Thanks for your reply.
So, basically, it will be impossible to use the phone port on this device?

However, I discovered that the official firmware from Telstra is also based on an older version of OpenWrt. In that firmware, the phone port works as expected.

In short, yes - unless you do the driver development.

(Presumably) Proprietary drivers and VoIP software of the OEM firmware won't help with that.

The ZTE MF286D works fine with RJ11, but... it is just an LTE router.
It would be nice if it was easy to utilise the IPQ40 (MDM9250) driver for IPQ80 (RG500Q-EA),but...

is the fsx/ ata device a feature of the modem?

I don't see that listed in the Quetel documentation it only mentions UAC

I recently obtained drivers for the RG500Q-EA modem. The download links for these drivers are provided below.

Is it possible to use these Linux drivers for OpenWrt?
