problems to send/receive Fax with FXS

Unanswered Question
Apr 26th, 2009

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.

I have this problem too.

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
