Using traditional telephony like PSTN is highly stable at this point in time. The downfall is costs through carriers or providers. Often companies can guarantee QoS in the 99.9999%+ range using PSTN.
DVP or direct voice peering is becoming more popular as carriers have developed ways to utilize things like the MPLS network. Also very stable and less costly provided it's used in a mass environment, otherwise, stick with PSTN.

QoS Quality of Service
Even though IP telephony and VoIP are used interchangeably, IP telephony refers the ability of users to mix-and-match third-party hardware and software.It is a best-effort network without fundamental Quality of Service (QoS) guarantees.
Static aspects of QoS management involve setting predefined parameters and configurations for network traffic handling, such as minimum bandwidth guarantees or priority levels. Dynamic aspects involve real-time adjustments and optimizations based on current network conditions, traffic load, and performance requirements. Dynamic QoS management is more adaptable and responsive to changing network conditions compared to static QoS management.
Loss of Quality of Service (QoS) guarantees
QoS is Quality of Service. Basically it prioritizes VOIP calls.
QoS (Quality of Service) strategy
QoS mapping for a wireless network - Mapping of QoS names of one protocol (e.g GSM GPRS) to the names of another protoco (e.g. WAP 3GPP.) More genrally, mapping of one QoS lassification to another.
