Re: Cannot allocate SIP call because device is fielding too many calls, (notification --00767)

I'm currently facing the same issue :-/
According to previous given solution (above), I wish to increase the maximum number of SIP calls on the SSG5 device. I read it is possible to modify the maximum number of SIP calls for a SSG5  to 32 :

set env max_sip_call_num=32

Should it be possible to increase this value to 24, in order not to consume too much ressources, by using this sentence ? Is this value (24) allowed ?

set env max_sip_call_num=24

Sorry to ask this but is it possible to export the cfg txt file, add this line (and where ?) to the file and then import the modified file ?
The Web GUI has no available menu for this parameter and I cannot use console mode.

Regards
