Issue receiving SMS with Kannel - Using USB Modem

Tom_R · October 16, 2024, 11:33pm

Hi, I configured Kannel with my USB Modem and sending SMS is successful. But incoming SMS isn’t working.

I tried some different configurations and haven’t found one that works yet for receiving SMS. Here’s my Kannel config:

Hi, have you watch kannel log and playsms.log during receiving sms tests ?

tail - f logfilehere

Anton

Tom_R · October 17, 2024, 9:23am

Hi Anton, Playsms log nothing happens when new SMS comes in… And kannel.log shows this, nothing that indicates a new SMS:

Should be something in /var/log/kannel/smsc-gsm1.log or gsm2 depends on which device used

Anton

Tom_R · October 17, 2024, 8:53pm

gsm1 and gsm2 are using same log file. I pasted it here can’t see anything when I test incoming SMS:

Try again and watch smsbox log, it should be something written in 1 of those Kannel log, then you’ll know why its not showing in playSMS

anton

Tom_R · October 18, 2024, 3:18am

I checked smsbox.log and can’t find anything in there either. Maybe its kannel config issue? This was smsbox log as follows:

This should be from a working Kannel:

github.com

playsms/playsms/blob/1.4.x/contrib/kannel/kannel.conf

# CORE
group = core
admin-port = 13000
admin-password = KANNELADMIN_CHANGE_THIS
status-password = KANNELADMIN_CHANGE_THIS
log-file = /var/log/kannel/kannel.log
log-level = 0
access-log = /var/log/kannel/access.log
smsbox-port = 13001
store-type = spool
store-location = /var/spool/kannel/store
smsbox-max-pending = 100

# SMSBOX
group = smsbox
bearerbox-host = localhost
bearerbox-port = 13001
sendsms-port = 13131
sendsms-chars = "0123456789+ "
log-file = /var/log/kannel/smsbox.log

This file has been truncated. show original

Except smpp parts it seems your config is about the same.

So I dont know why your message not coming to Kannel, have you check your sim card in a real phone and see if you can receive SMS on it.

Tom_R · October 18, 2024, 9:38pm

I tested my USB Modem in a windows app for sending and receiving SMS and it was working:

Maybe it’s a issue with init-string? I heard people trying different init-strings worked for them.

anton · October 18, 2024, 11:02pm

Ok, try again, this time with:

message-storage = "SM"

(your settings sets to ME)

See in group = modems block

Also you have 2 entries with the same id in group modems, give the other another id, like generic2 perhaps, or remove the block

Tom_R · October 20, 2024, 8:51pm

I tested out setting message storage to SM and didn’t see any difference.

Also I tried removing one of the modem groups and it led to some issues with Kannel. Changing id in group modems also led to this error: 400 Answer: <Sender missing and no global set, rejected>

anton · October 21, 2024, 6:27am

What is your modem brand and type ?

Share the link, maybe it has some settings need to be set in init

Also re-share your final kannel conf (the one with SM)

Tom_R · October 22, 2024, 1:26am

I found the model which is “Quectel EC25-AU 4G LTE” It’s a 8 ports modem.

It says on the page to install the drivers, I have them on windows but not on the virtualbox. Heres the modem page: This product is no longer available.

And heres the final kannel config:

anton · October 22, 2024, 6:58am

Ok, I have no idea, and I never work with that modem. Maybe you can try first with gsm modem that known to work normally with Kannel, like those wavecom 1 port gsm modem ?

anton

Azaman_Suleiman1 · October 26, 2024, 6:41am

add catch-all= true
Please check yr get-url which is different and seems inaccessable (are you using ngrok?)
e.g for the get-url that i have used
get-url = “http://x.x.x.x/index.php?app=call&cat=gateway&plugin=kannel&access=geturl&t=%t&q=%q&a=%a&Q=%Q&smsc=%i”

Tom_R · October 26, 2024, 10:01pm

Hi, I tried a few different configurations and I ended up getting a couple messages to come through. I added the catch-all parameter and tried localhost and using my main url. I’m using ngrok so sometimes it won’t be accessible.

The one change that ended up getting me some messages was when I changed message-storage from message-storage = SM to message-storage = ME. For some reason it will get some messages but not receive any new messages.

Heres the kannel config I ended up with:

CORE

group = core
admin-port = 13000

log-level = 0
