Hi, on mod_sofia.c there's this line of code: header = (tech_pvt->cid_type == CID_TYPE_RPID && !switch_stristr("aastra", ua)) ? "Remote-Party-ID" : "P-Asserted-Identity"; If you have an Aastra phone, you get header = "P-Asserted-Identity". Since I've snom phones and I'd like to get header = "P-Asserted-Identity", which var should I set to do it? I've tried setting sip_cid_type=pid before bridge, inside bridge and exporting it also. No luck. I suspect my compiler (gcc version 4.7.2) execute AND before ==! :( Any help?
