Asterisk attribute

i’m wondering how many sip extension doen asterisk accept and if it depend about the specification of my hardware i need an example so plz help me in that

Hi !

The number of sip connectins is only limited by the hardware.

How much can your hardware handle ?
See here: … mensioning

If you want to run a PBX, then asterisk is the right choice.

But if you want to run a SIP router, you might wanna go with SER (Sip Express Router) - Asterisk is not designed to be a SIP router, nor is SER a PBX.
