[Freeswitch-users] Openzap: every second incoming call fails

[Peter P GMX]

We have a strange Issue on Openzap with a Digium PRI card (Digium TE220
inkl. VPMOCT064 Octasic DSP-based echo cancellation module)

Every second incoming call is successfoll, every second incoming one
fails. For me it seems as if FS tries to use a channel which may be
still occupied?

Anybody has an idea?

Last hangup from successful!! call:
