I get the following probleme with a sagem ata 101s equipment and the 1.8.7 astersik version.
The ata send the register packet and asterisk does not respond.
With tcpdump, I think I found the problem.
There is no tag parameter is send whith the From: indication.
I did some test with netcat and manualy add a tag parameter and it works.
For that sagem there is no forware update so
Question :
Is there any asterisk parameter to “bypass” the missing tag parameter ?
I believe that there is a parameter which controls pedantic SIP compliance (with “pedantic” in its name) which recently changed from defaulting to false to defaulting to true. However, it should be returning a 481 response:
if (sip_cfg.pedanticsipchecking) {
/* If this is a request packet without a from tag, it's not
correct according to RFC 3261 */
/* Check if this a new request in a new dialog with a totag already attached to it,
RFC 3261 - section 12.2 - and we don't want to mess with recovery */
if (!p->initreq.headers && req->has_to_tag) {
/* If this is a first request and it got a to-tag, it is not for us */
if (!req->ignore && req->method == SIP_INVITE) {
transmit_response_reliable(p, "481 Call/Transaction Does Not Exist", req);
/* Will cease to exist after ACK */
} else if (req->method != SIP_ACK) {
transmit_response(p, "481 Call/Transaction Does Not Exist", req);
sip_scheddestroy(p, DEFAULT_TRANS_TIMEOUT);
} else {
ast_debug(1, "Got ACK for unknown dialog... strange.\n");
}
return res;
If turning off pedantic mode doesn’t help, and in any case, because of the lack of a 481, you need to collect SIP debugging information, see wiki.asterisk.org/wiki/display/ … nformation
I suspect the REGISTER is getting blocked before it reaches Asterisk.
so
