I'm configuring ATA 186 right now and the ATA is already registered to CUCM using SCCP. To call outside number, i use 9 as an access code and i'm using mgcp gateway with E1 line to PSTN.
I have configured the ATA with audio mode = 0x00150015 and connect mode = 0x90000400.
In the mgcp gateway, i added the following command :
no ccm-manager fax protocol
mgcp modem passthrough voip mode nse
mgcp modem passthrough voip codec g711ulaw
mgcp fax t38 inhibit
But the fax cannot dial out. If i connect anolog phone to the ATA, i call outside number and analog phone can accept outside call.
Does anybody have any idea about this problem?
