Hi,

I am trying to customize the reason phrase using t_reply.

I noticed that we can not set the reason phrase when the code is in the 6xx range

Kamailio TM is setting the reason phrase to "unknown" or to a default one.

For example :

t_reply("603","My custom reason phrase");

Will send "603 Decline"
