SIP URI

How do I set a dial plan for SIP URI, I want sip uri routed directly to its destination, rather than forward to the ITSP.

Just create a trunk which is only used for outbound direction and don't set the outbound proxy. Then in the replacement part of the dial plan you can put the URI as you wish. The PBX will follow the RFC3263 rules for routing the request.

Hi all!

 

pbx newbie here. I can't find out how to get a SIP URI through Snom One without getting changed.

 

Dial plan seems to have been built without the accomodation for SIP dialing to be done through it?

Please see http://macnugget.org/projects/asterisk/page7

 

My current dial plan (to keep thing simple) is: Pattern: * , Replacement: empty

Guess I'm after the same thing as shopcomputer?

Did you also assign the dial plan to the domain and/or to the extension?

Yes, I've tried both. Can't figure out how to build a dial plan that doesn't modify the SIP URI (info@intertex.se) dialed. It works fine for calling ordinary phone numbers with the simplest dial plan (pattern: *, replacement: empty). Calling i.e. 90510 gets converted to sip:90510@sip1.netatonce.net;user=phone which is fine.

 

However, a complete SIP URI i.e. 9902@qxip.net doesn't work cause the dial plan changes it to sip:9902@sip1.netatonce.net;user=phone (argh!). It replaces the domain (qxip.net) with the domain name of the SIP Registration Trunk (Generic SIP Server) of my broadband supplier and ITSP, Netatonce. Calling info@intertex.se doesn't work at all (SIP/2.0 404 Not Found) with the simple dial plan as above. Note: sip:info@intertex.se is not in use anymore.

 

I've tried |^([a-zA-Z0-9&=+\$,;?\-_.!~*‘()%]+@.+)|sip:\1| which gives nothing, unless I remove the "!" in the string. Then I get sip:info@intertex.se@sip1.netatonce.net;user=phone when all I want is info@intertex.se. If I register a Snom 320 directly on my ITSP's SIP server (sip1.netatonce.net) both phone numbers (routed to PSTN) and SIP URI's i.e. info@intertex.se works. Confused...

 

I would appreciate some, down to earth, guidance on how to build a simple dial plan that adds "@domain;user=phone" when a phone number is dialed but doesn't modify a complete SIP URI (an address containing the_@_sign). My country code is 46 (Sweden) and area code 40 (Malmoe). Thanks in advance... have a great day!

 

 

Update: After some testing my current, SIP URI capable, dial plan looks like this. Cool, because now recording works when calling a SIP URI

 

10;Netatonce;;112;

20;Netatonce;;^([0-9]{5,});

30;Netatonce;;"^([a-zA-Z0-9&=+\$,;?\-_.~*‘()%]+@.+)";sip:\1 (sip:\1 is the replacement)

90;Netatonce;;*;

 

Not bulletproof, but it works if the SIP URI doesn't start with more than four digits. Hoping that someone can improve pos. 20 in the dial plan or better the whole piece while you're at it.

I'm very impressed with Snom One after 2 weeks of newbie testing. Maybe I'm using it in a way not intended i.e. for phone numbers and SIP URI's alike.

 

Unfortunately there's an inbound problem. Trunk replaces the callers domain name with my domain name when someone calls my SIP address!?

So, if bill@microsoft.com call myname@mydomain.dyndns.org then my Snom phone will show Missed Calls from bill@mydomain.dyndns.org.

Please look at the From: "Bill Gates" headers below, in the Snom One Logfile, how the domain name changes. Most grateful if someone can remedy that.

The original design was respecting the URI; the orignal rule was: if there was a user=phone in the URI, then the PBX would change the URI and replace the domain. However, dealing with the reality in the SIP trunking market, we gave a little bit up on that for now and assume that all calls practically come from the "PSTN" or at least from a virtual PSTN. So far we have not seens any practical uses where the URI domain name was really relevant.
