Title: One way trransmission on ISDN PRI calls incoming only
Post by: leeav3 on September 20, 2012, 04:42:05 PM
Has anyone run into one way transmission on ISDN PRI calls only on incoming calls? The caller can hear me (on the mitel 5000) ,but I can not hear the originator (PSTN).  If I originate a call two way transmission works like a charm.  I am using National ISDN 2 variant.  Any help is appreciated.
