Hello
before I used Huawei 3g/2g modem to make calls by asterisk
Now I need to use 4g dongles with asterisk
I search in Huawei 4g modems but no model support voice and AT command
When I search about that found quectel modules can work with asterisk
but I don’t know any thing about this modules
so I have some questions
I want quectel dongle modules cheap price and support voice sms ussd with asterisk without Wifi and Gnss
I used Chan-dongle with Huawei modems but with quectel dongles can use same driver or other driver or can add Module driver with chan-dongle if i want to use twice in same system
and this modules dongle plug and play or need Firmware to work with Asterisk
and i need to change Imei I want to know if can yan use tools to change IMEI in Modules
Thanks so much
Hi Hithamadel,
I can recommend the modules below for your requirements
- EC21 (LTE Cat 1):
Features: Specifically supports SMS and has optional support for Digital Audio (PCM) and audio recording/playback.
Connectivity: Controlled via 3GPP AT commands and Quectel Enhanced AT commands, which is necessary for Asterisk integration.
Asterisk Compatibility: It is widely used in industrial gateways and telematics, applications very similar to your use case.
- EC200U (LTE Cat 1 bis):
Features: This is often a more modern and cost-effective “bis” version. It explicitly supports Digital Audio, VoLTE, DTMF, and SMS.
Protocols: Supports a wide range of protocols including TCP, UDP, PPP, and SMS.
These are professional-grade modules. While they are “plug and play” in the sense that they are recognized by the Linux kernel via the USB serial driver, you will need to configure the Asterisk configuration files (like dongle.conf) to communicate with the specific serial ports. Firmware is pre-installed, but you must ensure you purchase a variant where Voice/VoLTE is enabled, as it is sometimes listed as an optional feature
Also, IMEI modification is not supported.
Thank you and have a nice day!
Thank you so much
