Maybe someone from the list can share some information about the path module. Why can the path module only add either the received parameter to path or the flow token with the ob parameter, but not both.

Does the RFC mandates it? I didn't find anything like that and was wondering because the source calculates max length of the parameters with following: 

>> /* maximum possible length of suffix */

>> suffix_len = strlen(";lr;received=sip::12345%3Btransport%3Dsctp;ob;>\r\n") + IP_ADDR_MAX_STR_SIZE + 2 + (add_params ? add_params->len : 0) + 1;

This looks like it can be possible to have both.

Best regards
