[Freeswitch-users] FreeSWITCH using same Call-ID for forked calls

Fri Mar 20 14:45:31 MSK 2015

The Call-IDs are different on each INVITE. Not the same as you claim.

Call-ID: 174ff657-48f7-1233-d586-080027f911ca
Call-ID: 174f7870-48f7-1233-d586-080027f911ca

The first part varies even though the others are the same.
