[Freeswitch-users] Two calls with same call-id

Fri Sep 13 09:42:58 UTC 2019

Thanks, Brian,

i think i have resolved my issue (a stupid FW ports issue ...), but still
interested to understand if this call flow can lead to issues on Freeswitch
(doesn't seem to be the case, as I really see freeswitch managing two
independant calls).
How can i send you a pcap ?
