Benoit,

You posted "rseq", but do you mean "cseq"? Is the issue you reference Freeswitch returning a 482 reply to a serial forked request?

I used your example and we tried FreeSWITCH. Thank you for your
suggestion.

Unfortunately we ran into massive issues we were not able to solve.

I don't exactly recall which one it was but it appeared in situations
involving:

* 100rel required
* parallel branches

It was either the issue that FreeSWITCH itself was dropping rseq
replies with same rseq number but different totags wrongfully as
duplicates.

Or it was the issue with those replies with different totags on the 2nd
leg being mapped to ONE totag on the first leg causing the original
sender to consider them a duplicates and dropping them.
