Set Calling Party Category for Calls on SS7 Trunk

Is there any way to set the Calling Party Category parameter for calls going out on an SS7 trunk? We are working towards replacing some legacy telecom equipment and need to be able to set the CPC value on calls going out to a certain carrier.

There’s not a way to do it currently without code modifications. If you’re familiar with chan_dahdi.c/sig_ss7.c at all, you could set it using the isup_set_calling_party_category() function from libss7 though.

Best of luck,

Thanks for confirming my suspicion; I’ve already been looking through the source code thinking I’ll have to change it. I’ve just got to get back up to speed on my C programming skills; they’re pretty rusty these days. That function name helps, so thanks for that.

Have a good weekend,
