Hello All,
It is actually X-ten's X-Pro UA which is causing the call transfer
problem. From looking at the message headers in the data packets I can see the
following line originating from X-Pro.
Allow: INVITE, ACK, BYE, CANCEL, OPTIONS
The Grandstream UA headers have the following:
Allow: INVITE, ACK, CANCEL, BYE, NOTIFY, REFER, OPTIONS, INFO,
SUBSCRIBE
I don't know why X-Pro is so limited. I had X-Lite [the limited version]
installed on the same PC. X-Pro is supposed to enable all supported features.
Anyone at X-ten care to comment?
I uninstalled both X-Lite and X-Pro and the reinstalled only X-Pro and
still get the same behavior.
Awhile back someone asked for a link or copy of Iptel's ser.cfg file. Is
that available for viewing? Can the link be posted again [assuming it was
before]?
Thanks,
G.

Yes, but I haven't tried
the transfer feature. Note that it is reponsibility
of end-device to
implement call transfer correctly. SER just processes call
transfer as
any other SIP transaction.If you find any explanations about the
roots of
the problem, please share it with us over the mailing list.

SER supports any responses, including "100 thanks for
calling", "101 we are trying
for you", "102 have a nice day, I'm
connecting your call", etc -- it is a configuration
option what you send
back. You just need to design a proper numbering plan and
return 484 if
GS's INVITEs include incomplete numbers.

can be set to send an INVITE after every button press, and will continue to
do so if the server response with incomplete address instead of 404 not
found.

[I haven't tried it yet].
No -- that would allow anybody who supplies
empty password successfuly
steal my incoming calls.
