hello,

thanks for your reply.

i have converted it via voice manner.

the problem that i meet now is regarding the sent and reception of fax.

when i plug analog phone behind ATA, the calls passes, but fax not yet.

the confguration of the CCME as follow :

voice service voip

modem passthrough nse codec g711ulaw

dial-peer voice 3 voip

destination-pattern 1..

session target ipv4:X.X.X.X

modem passthrough nse codec g711ulaw

fax rate disable

CODEC G711ulaw

Until now, the fax cannot been sent nor receive.

Is the configuration correct, or i need something else to pass the sent/reception

I'm waiting for your assistance .

Kind Regards
