==Troubleshooting==
If the IVRS isn't working, it could be because of one or more of the below reasons. Also follow instructions right below which can help to troubleshoot the problem.
=== How to Insert Sim card in the dongle ===
* Click on the [http://support.three.co.uk/SRVS/CGI-BIN/WEBISAPI.DLL/,/?New,Kb=Mobile,Ts=Mobile,T=Device,varset_pid=6174,varset_cid=6175,Case=EXT(EM80399) link] to view the steps.
* Click on the [https://www.youtube.com/watch?v=aRKIZ5VIqfI link] to view a short video to insert the sim.
=== ''Using the micro/nano and Jio sim cards'' ===
Data cards used here require full sim cards and if they are cut like in micro/nano card then they are not properly placed in the sim card slot. A new sim card without cutting it can be placed or if they are cut then external card support can be used to fix this issue. Also note that Jio sim cards won't work to make calls on this IVRS.
=== ''Data card not detected or not switching to network mode'' ===
'''opentty: unable to open /dev/ttyUSB2: No such file or directory''' error message is generally shown when the data card is not detected or if it's in modem mode. To fix it, below steps can be followed.
# Command used to check the device mode "lsusb".
# Command used to switch the device mode manually.
sudo usb_modeswitch -v 0x12d1 -p 0x1446 -M 55534243000000000000000000000011060000000000000000000000000000 -V 0x12d1 -P 0x1436 -s 30 -m 0x01
A gap of 30 seconds is needed before we see the switch.
=== To Resolve the existing call error ===
Command to resolve the error:
sudo rm -rf /var/spool/asterisk/outgoing
=== ''Audio quality is bad or nothing is heard'' ===
This could happen because of issues in audio file (.wav). Make sure the frequency of audio file is 8000, track is mono and is saved in 16-bit *.wav format. By default, audacity saves file in 16-bit *.wav format but frequency and track settings have to be confirmed. This will fix the audio issues.
== Ubuntu Kalpavriksha(IVRS Pre-installed) ==
Click on the link '''[https://drive.google.com/open?id=1CkIkRv5N2E6ggt2w-KAtb7DhYEKoOGfZ Kalpavriksha(With_IVRS).ISO]''' to download the ISO which includes IVRS1,IVRS2 and Modem switching shortcuts in the office menu..
But need to change the IMEI number,and set it to your dongle IMEI number before launching the IVRS1 and IVRS2. Command used to change the IMEI number is :
