Hello- I am in the process of adding a new provider to my asterisk box (both for outbound termination as well as inbound DID). They are going to be delivering and receiving traffic via SIP only. Now, in IAX via Voicepulse or others I know that I can simply have one registration statement along with an inbound context, then in extension.conf map the outbound context. from iax.conf: register => in-xxxxxxxx:xxxxxxxx@gw5.voicepulse.com from extensions.conf [voicepulse-in] exten => 212xxxxxxx,1,Dial(${PHONES1}&${PHONES2},30) exten => 212xxxxxxx,2,Voicemail2(u${PHONES1VM}) exten => 212xxxxxxx,3,Hangup I know this way I only have to register once, but can receive calls on several inbound DID numbers without any problem, provided they are all mapped similar to what I have above within extensions.conf. My question is whether or not the same thing will work for a sip provider, as it will be pretty cumbersome from a networking standpoint to have a registration statement for each DID (as opposed to simply having a new extension statement). In the syntax of the sip registration statement it appears to always end with the /extension that is supposed to be associated with that account. Can the /extension be left off of the statement in sip.conf, and picked up in the same way DID's are used in iax.conf? If not, why are there separate methods for registering each protocol, would seem cleaner to have a consistent way of dealing with this. Regards, -Steve
