In sofia.c:<br>

if (ping_freq) {<br>
if (ping_freq >= 5) {<br>
gateway->ping_freq = ping_freq;<br>
gateway->ping_max = ping_max;<br>

switch_log_printf(SWITCH_CHANNEL_LOG,<br>
SWITCH_LOG_ERROR, "ERROR: invalid ping!\n");<br>
}<br>
}<br>
<br>
<br>
<br>
Is there a reason why To and From fields don;t contain the register<br>
username? This seems to break some other vendor gateways.<br>
<br>
