15 Emergency Calls
Even if the telephone is not registered to the PBX, it is possible to make
emergency calls. The sip proxy ip parameter in the configuration file,
defines where the telephone sends the INVITE with the SOS number.
No registrar is required for this.
For more information how to set up the sent A-number, see Emergency
Calls, SOS calls (5/15431-ANF90143) in the CPI library.
