[Freeswitch-users] B-Leg / A-Leg Race Condition

[Mike Burlingame]

The M6 on the other side does not have any options to delay the invite also broadsoft support is saying due to the ACK on the B-Leg (Broadsoft side) that they see no reason to delay the invite.

This only happens on 1 out of 30-45 calls and does not seem to be resource related

I will try to work with Broadsoft to see if they can delay the invite

Thanks for your feedback
