 Please see ticket #342 for info. Basically there are few settings to configure to make PJSIP sends smaller packet:
- 1. Configure PJSIP to send compact form of SIP headers, by setting {{{PJSIP_ENCODE_SHORT_HNAME}}} macro to 1 in {{{config_site.h}}}. This will reduce SIP message size by approximately 50 bytes.
+ 1. Configure PJSIP to send compact form of SIP headers, as follows. This will reduce SIP message size by approximately 50 bytes.
+  {{{
+   extern pj_bool_t pjsip_use_compact_form;
+ 
+   // enable compact form
+   pjsip_use_compact_form = PJ_TRUE;
+  }}}
  1. Suppress the inclusion of ''Allow'' header in outgoing requests, by setting {{{PJSIP_INCLUDE_ALLOW_HDR_IN_DLG}}} macro to 0 in {{{config_site.h}}}. This will reduce SIP message size by approximately 86 bytes.
  1. Suppress the inclusion of SDP {{{rtpmap}}} attribute for static payload types, by setting {{{PJMEDIA_ADD_RTPMAP_FOR_STATIC_PT}}} macro to 0 in {{{config_site.h}}}. Note that this setting should not cause bad effects for communication, since SDP {{{rtpmap}}} attributes for static payload types are optional. This will reduce SIP message size by approximately 65 bytes.
