While IP PBXs are usually deployed for inter-corporate communication, SIP Trunking further extends the capabilities and enables communication outside the organization over IP cloud.

Inflexibility:

Traditionally businesses buy TI Trunks/PRI connections from the Telco Service Providers to connect them with their on-premises TDM Gateway infrastructure /PBX systems. When there is a need to extend the existing network enterprises usually have to purchase channels in increments of 24 or 32, regardless of their business need. PRIs could not scale flexibly on a per line basis. Also enterprise on-premises gateway infrastructure also need to be scaled, upgraded or provisioned.

Complex & Costly infrastructure:

SIP Trunking eliminate the need to conventional PRI connections and deploying the Media Gateways infrastructure thus offering significant cost reduction in managing the service.

Reducing operating expenses:

Ongoing Telephony costs and operating expenses are reduced considerably as it eliminate the costs associated with ongoing support & maintenance of Media Gateways

Maintenance:
