Monitoring ASR for Mobile Ports
ASR monitoring of the last 40 calls occurs for all mobile ports. If the ASR (ASR2) is lower than 30 percent, an alarm
is generated at the corresponding port and the port is blocked. The port is then restarted and a corresponding entry
appears in the
protocol.log
file (ASR). The port is then unblocked.
The following entry in the
pabx.cfg
causes the mobile port to block automatically when this error occurs three
times in a row:
ASRBlock=On
When
ASRBlock=Off
is used, the port will be restarted and will remain open.
The following parameter in the
pabx.cfg
file allows you to change the default value (30% for 40 calls):
UMTS=ASR[<percent>,<number of calls>]

Prepaid SIM cards are an alternative to mobile telephone SIMs with a contract. Instead of being billed retroactively,
prepaid SIMs are paid for in advance and then recharged when they run out.
The advantages of prepaid SIMs are:

No monthly basic fee

Cost control

No surprises resulting from unexpectedly high mobile telephone bills
When the account is empty, it can be recharged. The recharging methods for prepaid SIM cards of different carriers
vary:

Recharging via SMS/USSD

Recharging via call to a defined number

Recharging via DTMF

Automatic recharging via direct debit
When prepaid SIMs that do not recharge automatically (e.g. through a credit card) are used in an ECOTEL, it is
possible to recharge them directly from the system. The following requirements apply:

The SIM is registered and no connection is active.

Exact knowledge of the mobile carrier-specific recharging procedure exists.

One valid prepaid voucher exists for one recharge.
UMTS=ASR[20,35]
Transmission errors, truncated connections, incorrect or altered recharging proce-
dures can prevent successful recharging. Please bear in mind that 3 incorrect re-
charge attempts (per SIM) can result in blocked SIMs. Recharge SIMs at your own risk.
