Hi Everyone,

I would like to ask if it is possible to change incoming callerid type. My Telco callerid is using DTMF and it is detectable on my grandstream FXO gateway. Now, this callerid is assigned on one of my Digium FXS port and set to have a callerid type output as Bellcore. Output of that FXS is terminated on one of the trunk of my old pabx. Unfortunately, the pbx has no support for DTMF and it is only available for Bellcore callerid type.

Please need your idea on this one and please how would I do it on asterisk configuration.

Thanks in advanced
