Hello,
is it possible to return the call back to the same OpenSIPS instance
when using topology hiding with Call-ID header encoding?
It doesn't work for me. The call flow is:
1. caller -> OpenSIPS, call_id_1 = 39e20b8211b311ef9f35a0369f28db67@X.X.X.X
2. OpenSIPS -> the same OpenSIPS, call_id_2 =
PNiupb663sWqpd38kW1sITWF4YSZ1cFgODEw1emUldnJfUgxHay0ycnEBUVpETGBnYnV.b1pc,
encoded call_id of the first leg
3. OpenSIPS -> callee, call_id_3 =
PNiupb663sWqpFAgoHBsIQ2V6IxM3MQ1YUh4EeCMNEhYvXzMmCXgzAiEOLS4dRDYkBSgiLyMNPxIrATE9djgKBS83Bh8gARIGKwUzGwVnMnU2Ig--,
encoded call_id of the second leg
This scheme doesn't work for a subsequent requests from the first
OpenSIPS to itself including ACK to the INVITE transaction. It doesn't
work because OpenSIPS decodes call_id_2 when it receives the request and
decoded call_id doesn't match with the call_id of appropriate dialog
found by DID:
DBG:dialog:api_match_dialog: We found DID param in R-URI with value of

Could you please explain, is it somehow possible to use call_id hiding
with call loops?
