Of course, I added the following lines to original
kamailio.cfg file. My
aim was to change nexthop or change destination address which comes inside
msrp frame. If I could do this, I can send MSRP messages to wherever I
wanted. However, It doesn't let me to manipulate the variables inside msrp
frame. By doing $msrp(nexthop) = something or using msrp_set_dst function.
#$msrp(nexthop) = ("msrp://192.168.1.100:30000/r02XBu00;tcp");

Could you share your minimal config and related

This will be interest for me to look.

Hello,
I'm using Kamailio MSRP module as a MSRP relay, It works successfully
when I send one-to-one MSRP messages. I am having trouble while sending
msrp messages to multiple receivers. My question is that can I use this
module to forward msrp messages not just one receiver, but multiple
receivers? Can this module be used like MSRP switch?
Thanks in advance.
