The vendor seems to expect a valid username in To field. At the moment we had to disable pings, because the remote side replied with Forbidden and put our address to a blacklist. I will dig for more details.

Those are perfectly valid OPTIONS packets, how exactly is the vendor claiming it breaks them?

It appears that in the OPTIONS ping packet, To and From fields contain
only the domain name.

In sofia.c:

           if (ping_freq) {
                if (ping_freq >= 5) {
                    gateway->ping_freq = ping_freq;
                    gateway->ping_max = ping_max;
                    gateway->ping_min = ping_min;
                    gateway->ping_monitoring = ping_monitoring;
                    gateway->ping = switch_epoch_time_now(NULL) + ping_freq;
                    gateway->options_to_uri =
switch_core_sprintf(gateway->pool, "<sip:%s>",
                        !zstr(from_domain) ? from_domain : proxy);
                    gateway->options_from_uri = gateway->options_to_uri;
                } else {
                    switch_log_printf(SWITCH_CHANNEL_LOG,
SWITCH_LOG_ERROR, "ERROR: invalid ping!\n");
                }
            }



Is there a reason why To and From fields don;t contain the register
username? This seems to break some other vendor gateways.


thanks,
