GMS callback

[peter.nagy]

Hello!

Do you know if there any specific callback chat-script for GSM?

There is a Cisco 1751 with a WIC-2AM module. Callback just works fine with normal modem, but when i use a gsm phone the callback process hung up when the phone picks up the call.

Hello Peter,

here is a script that works with a Nokia, not sure which GSM you have. If you have a Nokia, make sure you select ´Analog dialin´ and noy ´V.110 Emulation´:

chat-script script ABORT ERROR BUSY "" "AT" OK "ATDT \T" TIMEOUT 30 CONNECT \c

chat-script init "" "ATZ\r ATX3\r ATS0=1\r AT%M4\r"

chat-script offhook "" "ATH1ZX3" OK

chat-script callback ABORT ERROR ABORT BUSY "" "ATX3" OK "ATDT \T " TIMEOUT 60 CONNECT \c
