> It seems it was trigged, if we did not set the name on the channel. When we configured the name property on the channel, everything worked. So i guess according to Asterisk, the problem is in the file {code}res_pjsip_caller_id.c{code} at line 415. The validation check {code}if (id->name.valid) {{code} is true, but {code}id->name.str{code} is 0x0 when name is not set. This causes strlen to fail in the line {code}int name_buf_len = strlen(id->name.str) * 2 + 1;{code}
> The following code was bogus:
> {code}
> // OutboundCallerID is fetched from mysql though ODBC, example: 22556644
> if ("${OutboundCallerID}" != "") {
> Set(CALLERID(num)=${OutboundCallerID});
> }
>
> Dial(PJSIP/${number}@${TrunkName},${DIALTIMEOUT},${DIALOPTIONS}U(onConnect,${CallInfoId}));
> {code}
> And the following works:
> {code}
> // OutboundCallerID is fetched from mysql though ODBC, example: 22556644
> if ("${OutboundCallerID}" != "") {
> Set(CALLERID(num)=${OutboundCallerID});
> Set(CALLERID(name)=${OutboundCallerID});
> }
>
> Dial(PJSIP/${number}@${TrunkName},${DIALTIMEOUT},${DIALOPTIONS}U(onConnect,${CallInfoId}));
> {code}
> Regarding the "pjsip set logger on" - it never reaches to this. No SIP packages is set, so this is just empty.
