Hi,


I have UCM6.1 cluster in main office, in remote side I have around 60 IP phones.


I can dial between remote site and main office with FXS port, I can receive and send faxes between phones located in remote side but I can not send and received between main office and remote side and from PSTN


how can I solve this issue??


regards,


I have 8FXs port in a 2821.

Try adding these commands:


remote:


voice service voip

fax protocol none

modem passthrough nse codec g711ulaw


voice-port 0/0

input gain -5

output attenuation 3



main office:


voice service voip

fax protocol none

modem passthrough nse codec g711ulaw


network-clock-select 1 t1 0/0/0
