{"abstract":"This study aimed to implement the “VOIP telephony for NONESCOST communication system”. The main objective of this study is to implement the VOIP telephone system to NONESCOST using open source software, to evaluate the efficiency of the implemented VOIP Telephone System of NONESCOST, and to evaluate the cost-efficiency of the VOIP Telephone System of NONESCOST. A Performance and Pilot testing was used as a research design for conducting study on comparing the Performance of existing devices which is the basic telephone provided by the local service provider. To achieve the objectives of this study, the researcher used a self-made questionnaire and was validated using criteria developed for evaluating survey questionnaire by Carter V. Good and Douglas B. Scates. The respondents of the self-made questionnaire are the five (5) offices that was deployed of the VOIP Phones with 25 items question and five-level Likert scale. A data was gathered and tabulated to get the weighted mean. The result was very relevant that implies that the implementation of VOIP-PBX for NONESCOST communication system contributes a big impact in terms of simplification of their communication system.","abstract_source":"original","authors":["Jano Tabor","Reyjean Porras","Alex Facelo","Roel Palmaira"],"date":"2022-08-04","doi":"10.5281/zenodo.6964540","id":467,"issue":5,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"570f9a4752e2359fc5174fe8bf4b3501dafa95632af8eccbe2f131e6abc479fd","schema":"scimatic-article/1","title":"VOIP Telephony for NONESCOST Communication System","volume":3}

1. The record, from the token's own metadata:

printf '%s' "$(curl -s https://scimatic.org/nft/articles/467.json | jq -r .canonical_record)" | sha256sum

2. The hash stored on chain (contentHash(467)):

curl -s https://rpc.scimatic.net -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_call","params":[{"to":"0x0E596B4bb924937aA35D9b342A90347ed6F05eF8","data":"0xf3e0c29000000000000000000000000000000000000000000000000000000000000001d3"},"latest"]}'

The two must be equal (the second with a 0x in front).
