Good morning. Is any way in freeswitch to force to use same source port for outbound calls to gateway? For example i have following gateway configuration : <gateway name="PRO"> <param name="proxy" value="10.10.10.44"/> <param name="username" value="not-used"/> <param name="password" value="not-used"/> <param name="context" value="from_PRO"/> <param name="register" value="false"/> <param name="register-transport" value="tcp"/> <variables> <variable name="verbose_sdp" value="true"/> <variable name="absolute_codec_string" value="PCMA,PCMU" direction="outbound"/> </variables> </gateway> When i send outbound calls to gw PRO. FS choose random source port for every attempt. Due to it Gateway PRO fail to authenticate it.
