### Description This new code in pdttree.c is not correct for this new pdt mode, it just print's a debug log instead of error. The return value should be 0 instead of 1 in case _pdt_mode is 1 otherwise it will still not start. <code> if(_pdt_mode & 1) { LM_DBG("prefix already allocated [%.*s/[%.*s] - ignoring\n", sp->len, sp->s, sd->len, sd->s); return -1; } else { LM_ERR("prefix already allocated [%.*s/[%.*s]\n", sp->len, sp->s, sd->len, sd->s); return -1; } </code> ### Troubleshooting #### Reproduction #### Debugging Data #### Log Messages #### SIP Traffic ### Possible Solutions ### Additional Information * **Operating System**: -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3626 You are receiving this because you are subscribed to this thread.
