SIP trunks set up the way your switch already expects
For carriers connecting their own switch into QALLVO — how a trunk gets set up, and what is agreed before it carries live traffic.
Interconnect
SIP trunking
IP-authenticated or registered trunks, codec and capacity agreed up front, with test traffic before commercials.
Authentication
IP or credentials, your choice
Static IP allow-listing or SIP registration with credentials — pick whichever fits how your switch already connects out.
Codecs
Negotiated per trunk, not assumed
G.711, G.729 and others agreed at setup, so transcoding is a decision made once rather than a surprise in production.
Capacity
Concurrent channels set before go-live
Channel counts are agreed as part of onboarding, with headroom discussed up front rather than found the hard way.
