[SR-Users] Kamailio 4.4.1 REGISTER Parse Error in PCSCF

[Carsten Bock]

Hi Mihail,

you could also see the REGISTER in the PCAP, if you did not configure
your DNS/BIND properly...

Thanks,
Carsten

P.S.: I regularly test Zoiper with our own setup, it works... and it
even should work with the 4.4 version, you're running.
