Help needed with outgoing calls on UK PRI interface
Hi, I have recently just installed a UC520 with the T1/E1 card for my customers ISDN30 line. we can receive incoming calls perfectly OK but when we try to dial out we get a dial tone but then we get a message back from BT saying the number is not recognised. where am I going wrong.
