I am testing the TERASIP using an application wiht TAPI3, I can receive calls, make calls, but when I do BlindTransfer, the call is transfered but my application wait for 2 minutes and receive Time out error. I tested using SipX and Trixbox like PBX. Could you have some idea what happening?.

Thanks in advance,

Milton,

thanks for checking out TERASIP!

First thing you should know is that TAPI3 BlindTransfer is a
very bad function and you should not use it! This function is
absolutely different from TAPI2 lineBlindTransfer.

Instead of executing the TSPs blind transfer feature,
TAPI3 BlindTransfer actually does an attended transfer,
just in a way as if you would do it yourself but with the
big drawback that it executes synchronously, and can't
be cancelled. It does not call the TSPs blind transfer feature!

To solve your problem though, you could try to send the
refer without subscription (TSP configuration >> Advanced
>> Issue REFER without subscription).

If it still doesn't work, you can post a Wireshark trace here
and we'll try to have a look what's going on!


Best regards,
