[VoiceOps] Siemens HiQ 8000 question

[Colin Brown]

Does anyone have any experience with the Siemens HiQ 8000 series? I've got a customer with one of these hunks of junk that is sending a BYE instead of a CANCEL in this situation below:


1.1.1.1 ---INVITE---> 2.2.2.2
1.1.1.1 <--TRYING-- 2.2.2.2
1.1.1.1 <--183 SP-- 2.2.2.2
1.1.1.1 --BYE--->     2.2.2.2
1.1.1.1 <--200ok-    2.2.2.2
1.1.1.1 --CANCEL-> 2.2.2.2
1.1.1.1 <-487 expected back-- 2.2.2.2

While I understand that a BYE is legal according to the RFC 3261 it really breaks with the spirit of it and interoperability.  Does anyone know how to configure the Siemens HiQ 8000 to send a CANCEL instead of the BYE in this situation like any normal SBC would?



THanks,
