[Asterisk-Users] zt_rec: Unknown error 500

[Scott Stingel]

Hi Michiel-

This may be related to a PRI frame buffer overflow problem that I get in
high-volume IVR applications.  I get a lot of these errors mixed in with
frame errors.   In my case its load related.  Mark and Martin at Digium have
said they'll be looking into improving the buffering mechanism.
