I was just thinking of an alternative soln. for this issue.
How about sending a 500 Error response with Retry-After header, so that UAC
could try re-sending the UPDATE request after a time decided by Retry-After
header value?
Then we could probably expect the call to connect, in the meantime, afte
Dale,
How would you deal with re-Invite collisions between MOH server and the UA
that you placed on hold? The normal re-Invite back-off will not work
properly if it was your UA that established the call to the held UA
(otherwise you can just use Retry-After header). You probably need a section

1) SIP/SDP call establishment procedures for T.38
are specified in Annex D/T.38 (2005/09).
This is normativ for T.38 implementations.
2) The term (G.711) pass-through mode is misleading, because there is a

Hi,
The best option is to contact Broadsoft. I do not know the
implementation of fax support in Broadsoft's products but typically, you
start a fax call using a vo-coder (G.711 in your case) and then some
implementations *may* switch to fax relay using T.38. Some
implementations do not support
Rohit,
You may be right, may be driven by configuration or may be because the client
didn't indicate the T38 capability its switching automatically to G711 Mode.

Hi
If I understand it correctly, Somesh is suggesting addition of T38 media stream
in offer from the endpoint whereas Neranza's query is how to make Broadsoft
initiate T.38 fax instead of Pass-Through on tone detection? I think Neranza
wants that Broadsoft should add T38 stream in the Re-INVITE
I think you will have to put something like this in SDP
m=image 1 udptl t38
a=T38FaxVersion:0
a=T38MaxBitRate:14400
a=T38FaxFillBitRemoval:0

Hello All,
I have a problem with sending a T38 FAX over a Broadsoft server.
I am sending to a PSTN FAX so the Broadsoft server is terminating SIP
point and it should send me REINVITE for T38 but it does not. It is just
accepting the FAX transmission over G711.
My question is there some specif
