Package: libexosip2-dev Version: 4.1.0-2.1 Severity: normal Dear Maintainer,
it seems that exosip sends JaK as keepalive when in udp mode. it sends \r\n\r\n when in tcp mode. the latter is the standard way for both tcp and udp modes as per rfc. digging in the libexosip source it seems that this is the issue: static int udp_tl_keepalive (struct eXosip_t *excontext) { struct eXtludp *reserved = (struct eXtludp *) excontext->eXtludp_reserved; char buf[4] = "jaK"; googling for it, it seems that this JaK causes others headaches too, so if possible, please change it to the standard \r\n\r\n thanks in advance, csaba mate -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.15.0-1-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US, LC_CTYPE=en_US (charmap=ISO-8859-1), LANGUAGE=en_US (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libexosip2-dev depends on: ii libexosip2-11 4.1.0-2.1 ii libosip2-dev 4.1.0-2.1 libexosip2-dev recommends no packages. libexosip2-dev suggests no packages. -- no debconf information
