Michael Newton commented on ASTERISK-28233:
-------------------------------------------

Looking over the recent commits, I am having trouble understanding how a single fixed endpoint is in any way useful? The idea of dundi is to send out a request to many peers, any of which might respond with an offer to complete the call. Am I misunderstanding what an "endpoint" is in pjsip terminology?

In our network, we have incoming calls from our PSTN carrier sent to a single server. That server does a dundi query of 100 hosted PBXs, one of which responds with, e.g. "SIP/12345678 at foobar_pbx" where "foobar_pbx" is configured as a dundi peer and a SIP peer with an IP address on the local network. How could this be replicated with this patch using a single fixed endpoint?

Also I am not a C programmer, but are both these things meant to be checking for an empty string? There are two opposite uses of {{ast_strlen_zero}} here.

{noformat}
if (!ast_strlen_zero(pjsip_outgoing_endpoint)) {
	ast_log(LOG_WARNING, "PJSIP calls require an endpoint to be specified explicitly (use the pjsip_outgoing_endpoint option in dundi.conf)\n");
	return -1;
}
/* Take IP/number and turn it into sip:number at IP */
if (ast_strlen_zero(ip)) {
	ast_log(LOG_WARNING, "PJSIP destination is empty?\n");
	return -1;
}
{noformat}
