Hi, when dialing a number, it appears the dial-sequence does not always complete. Sometimes it dials through fully, but other times I hear a fast busy tone in the middle of the dialing, and I see this event in the 3CX log:
SIP Server/Call Manager ID: 12294
Call or Registration to 44776@(Ln.10000@xxx) has failed. xx.xx.xx.xx replied: 503 destination is invalid; from IP:xx.xx.xx.xx:5060
Any idea what may cause this and how to fix? Thanks
