Hi,
As per RFC Retry after timer is different for UAS and UAC and hence they
both are not going to ReTry after same interval.
I hope I got you question right.
I am not able to see section in Red.

Hi,
Does RFC5876 describe an alternative method to RFC4916?
Or, is it intended to complement RFC4916 in a trusted environment
where RFC4474 is not supported, implemented?
The following paragraph is from section 3.2:
In one example, an established call passes through a gateway to the
PSTN.

See rfc3261 section 14.1's 491 text.
HI
I am sure this has been asked many times but I could not find a
definitive thread on how to resolve this. Moreover RFC 3261 section 14.2
is vague about resolving race conditions for Re-INVITEs. You could
directly skip over to offending section (in red) below for the issue in
question.
