[asterisk-users] High Volume Call Center SIP versus IAX2

[Danny Nicholas]

Just my opinion - Call Centers should be SIP trunked because IAX is more
prone to poor sound quality.  IN MY SHOP (shouting to make the point that
I'm not speaking for all Asterisk installations), the IAX quality is at best
40-50% of a SIP connection.

Subject: [asterisk-users] High Volume Call Center SIP versus IAX2

 

I wont say we are extremely high volume (40 concurrent calls) but I get
occasional complaints about quality.

 

Setup (at same location): 

Asterisk 1.4.26.2 FrontEnd

Asterisk 1.4.26.2 Gateway with Sangoma A108D card with 2 PRI and LDT1

 

Connected via IAX2 trunking on its own VLAN

 

Is IAX2 the way to go or would SIP trunking be better. 

 

I know its a pretty vague question but I am just trying to make sure I am
approaching the setup correctly.

 

Thanks
