Dear colleagues,
can someone help this engineer from Brazil? I will
translate his two questions:
1) When RRq fails in H.225.0 and there is a
retransmission, requestSeqNum is repeated. His question is, what does he use as
the timestamp? I presume it remains the same.
2) What happens with the timestamp when summer
savings time (clock is adjusted one hour ahead or behind) starts? I presume if
it changes outside a session, it is business as usual; if it changes in the
middle of a session, then it should stick to the original one, and start +,- 1
hour for the next sessions open.
Please copy any replies to him
at:
as he

Thanks!

Caro amigo Simão
Socorro! I need help!
Estou com uma dúvida a respeito de H.225 e não
estou achando a resposta: quando um RRQ falha por algum motivo e ocorre uma
retransmissão, o valor de "requestSeqNum" é repetido. Ver
abaixo:
"requestSeqNum in messages is used to
keep track of multiple outstanding requests. Any associated response messages
(success or failure) shall have the corresponding requestSeqNum returned with it.
Retransmitted messages shall have the same requestSeqNum. RequestSeqNum increments by 1 modulo
65536."
A dúvida é: o que acontece com o timestamp? Deve ser repetido
também??? Ou ele sempre aumenta?
Outra dúvida: o que acontece com o horário de verão? O
relógio volta ou avança 1 hora. O que acontece com o Timestamp nessas
situações?
Muito obrigado pela ajuda!
Um abraço
Zé
