[SR-Users] Kamailio crashing after comparing AVP with string

[Jurijs Ivolga]

Hi,

Just quick question, before sending some more debug info.

I just figured out that issue is related to dispatcher list, I'm using text
file. Following dispatcher list do not work:

1 sip:1.1.1.1;transport=udp 0 0 bla
1 sip:2.2.2.2;transport=udp 0 0 blabla

But if I use below one, it works without any issue:

1 sip:1.1.1.1;transport=udp 0 0
1 sip:2.2.2.2;transport=udp 0 0

Maybe my attributes are incorrect?

With kind regards,

Jurijs
