[SR-Users] unexpected char - status 6

[Daniel-Constantin Mierla]

Hello,


the second packet in the trace has \0 in the To header. Likely the
endpoints is changing the From/To headers and restoring them with uac
module is no longer working. Either don't auto-restore them or use uac
with dialog module to store the the values.


Kamailio 4.4 or newer should have a better detection of this case.

Cheers,
Daniel
