Hi,
If a endpoint-1 offers precondition as follows :
supported:precondition, 100rel
SDP Parameters
a=curr:qos local none
a=curr:qos remote none
a=des:qos none local sendrecv
a=des:qos none remote sendrecv
If for the endpoint-2 the precondition support is mandatory, then
what should be the answer for this offer
1) Should the call fail (i.e error response must be sent?)
2) Or according to the following text of RFC 3312
Note that the rules above apply to the desired strength-tag
"none" as
well. This way, a user agent that supports quality of
service but
does not intend to use them, adds desired status lines with
the
strength-tag "none". Since this tag can be upgraded in the
answer,
as described in Section 5.2, the answerer can request
quality of
service reservation without a need of another offer/answer
exchange.
Can the answer be the following?
a=curr:qos local sendrecv
a=curr:qos remote none
a=des:qos mandatory local sendrecv
a=des:qos mandatory local sendrecv
a=conf:qos remote sendrecv
Is my interpretation of the above text correct?
Thanks in advance
Regards
Bindu
