Re: [sr-dev] [kamailio/kamailio] 180 Ringing without Contact with TOPOS enabled (#1720)

@miconda

I'm sorry to write in this already closed issue, but I have a problem related to the fixes implemented to solve this problem. In particular I would like to ask you why, in case of TOPOS module enabled, the Contact is a mandatory header for 183 messages as implemented in commit 416d79b462986317f2c3a3ed8aa30a502d116095.

From RFC the Contact header is optional for all the 1xx reply messages.

I don't have any issue when I receive 183 messages without Contact header if TOPOS module is disabled. When I enabled it, instead, I fall in the mentioned check.

Thanks
