Checking GSM modules & SIP peers using asterisk
CLI
After installing the chan_gsm.so module, you can check the gsm modules
which you have enabled in the configuration. As shown in following command.
allogsm
*CLI>
Port Status InUse Provider Home Zone Signal Quality
1 (0) REGISTERED n "Rogers Wireless" y -82dbm
2 (0) REGISTERED n "Rogers Wireless" y -82dbm
3 (0) REGISTERED n "Rogers Wireless" y -82dbm
4 (0) REGISTERED n "Rogers Wireless" y -67dbm
The fields here can be detailed as follows:
* Port column is the index to the GSM port.
* Status should be REGISTERED.
* InUse column indicates if the GSM port is busy.
* Provider gives the name of the provider.
* Home Zone indicates if we're registered to our regular provider.
* Signal Quality indicates how good the signal reception is.
For signal quality, we can translate the measurements as follows:
# not measurable (not measured yet)
# -112 dbm is very low
# -97 dbm is low
# -82 dbm is ok
# -67 dbm is good
# -52 dbm is high
# -51 dbm is very high
Similar to above command many other at commands can also be used as
bellow,
allogsm
send at <port> "<command>"
where port is the gsm port, command is "at+csq" for checking signal
strength.
Similarly we have many at commands which we can give as commands.
(at commands are generic gsm at commands which can be searched in
the internet)
