[SR-Users] potential PRACK related topos bug

[Henning Westerholt]

Hi Juha,

as there have been different changes to topology hiding modules in the last months, can you specify the exact minor version?

Cheers,

Henning

Test topology using K 5.4 where topos module is loaded in Proxy1:

   A - Proxy1 - Proxy2 - Proxy1 - B

A sends INVITE, B responds with 183 Session Progress, and A sends PRACK.

The result is that PRACK starts to loop in second Proxy1 instance instead of being forwarded to B.

If topos module is not loaded in Proxy1, it forwards PRACK to B as it should.

Also, if Proxy1 loads topos module, but A does not send PRACK, other in-dialog requests (e.g. BYE) work fine.
