I have a customer that previously had their PRI service with AT&T. They now cut over to TelePacific. They currently have a MICS 0x32 with 4.0 XC software. They had an existing 0x8 ASM and we piggybacked another 0x8 ASM for a total of 16 analog ports. They are able to receive faxe's but now they cannot fax out. They receive a transmission error. Any hints as to what may be causing trouble?
