[Asterisk-Users] zt_pri_error: PRI: Warning: unknown/inappropriate protocol discriminator received (00/0)

[Vasyl Rublyov]

I started to see this problem as soon as we connected to Verizon PRI 
(DMS-100 Switch) and it prints every 3-5 seconds.

[Verizon DMS-100 PRI] <====> [Lucent Merlin Legend] <====> [Asterisk]

Asterisk/LibPRI/Zaptel are built from HEAD CVS on Jul 10 2004.

Any help?
