[asterisk-users] Question about SS7

[Alexander Lopez]

SS7 does NOT play a roll in VoIP. The SS7 signaling that you are
describing is not really SS7 but signaling over a PRI using ISDN that
your provider uses to exchange information via SS7 to the other
carriers. 

 

To be blunt and I do not mean to be condescending in any way, but, if
you are using Asterisk and do not know what SS7 is, you don't need to
worry about it.

Subject: [asterisk-users] Question about SS7

 

Hi,

 

I have read about SS7 recently and learnt that it is a signalling
protocol used in PSTN for call management, setup, etc.  The thing that I
don't understand is how SS7 plays a role in VOIP.  When I make calls
between landline and Asterisk via PSTN, I don't need to do anything with
SS7.  Is it because the SS7 signalling is already done by Asterisk
already?  From the prespective of implementing Asterisk, what kind of
SS7 support is needed?  Is SS7 something needs to be concerned about
when using Asterisk with T1/E1?

 

I hope someone can help me to clearify these doubts that I am having.

 

Thanks,

Mark
