[SR-Users] topos and PRACK problem

[Daniel-Constantin Mierla]

Hello,

thanks for troubleshooting further. I haven't got the time to look at
the source code, but I expect that the b-leg attributes (contact, record
routes) to be set on 200ok for dialog (topos_d). I think for PRACK, the
routing information should be stored and taken from transaction (topos_t).

Cheers,
Daniel
