[sr-dev] Segmentation fault when MSRP frame is received

[Carsten Bock]

Hi,

did you properly configure DNS?
For each domain served by the relay the following DNS record must be
added to the name servers authoritative for the domain:

_msrps._tcp.example.com. IN SRV 0 0 2855 msrprelay.example.com.
msrprelay.example.com. IN A 10.0.0.1

Kind regards,
Carsten
