>          Components: Resources/res_pjsip_keepalive
>    Affects Versions: 13.7.2
>         Environment: Fedora 20

> When configured with the 'keepalive' option (keepalive = 30 in sip.conf), Asterisk sends periodic keep alive packets to peers. These packets as sent with content '\r\n\0' instead of 'r\n\r\n' as indicated by RFC5626 section 4.4.1.
> This has the potential to confuse clients and not be interpreted as 'ping' packets.
