In FXO gateway, it could pass through the incoming calls from the PSTN side

to the IVR of Asterisk directly. It depends on the hotline function in FXO

gateway.

Please check out the configurations as following in FXS gateway:

usr/config$ sysconf -service 1

usr/config$ bureau -hotline 1 61.33.33.33 (The IP address of Asterisk)

Please check out the configurations as following in FXO gateway:

usr/config$ line -config 1 hotline 9

After users dial the PSTN number into the FXO port, FXO gateway will enable

the dial out the number “9” to the IP side automatically. Users could get the IVR

from Asterisk while Asterisk answers this call.

Please pay more attentions for the third command in Asterisk. Asterisk will wait

for the extension number from the client side, that’s meaning it will detect the

DTMF. For the DTMF signal detection, Asterisk could support the In-Band,

RFC2833 and SIP info. Please make sure about this in the configuration file

which was named sip.conf.

Note:

z There is known issue in IVR mode. Users will hear the click-click sound while connecting

with FXO device with version 104. It is due to CNG function in FXO device. Please contact

with sales updated version or get the new one.

z For the updated firmware version, please disable this function to avoid this situation:

sysconf -silence 0
