This page provides a couple of tricks to ease working and debugging with FreeSWITCH
Contents
config snippets
dial by incoming domain
Typically, FreeSWITCH only looks at the destination number, so 1200@ackspace.nl is treated the same as 1200@illegaleshow.nl in the public dialplan.
This snippet routes all calls destined to either the illegaleshow.nl domain or the illegaleshow extension to 1200 in its own dialplan.
Note that there aren't many sip_to_host examples on the net (or the less predictable alternative sip_req_host for that matter, also see this stackoverflow thread):
- req or Request Uri is where the INVITE goes (he next hop address, a proxy if you will)
- To Uri is the actual destination to call
<extension name="Illegale show">
<condition regex="any">
<!-- sip_req_host -->
<regex field="${sip_to_host}" expression="illegaleshow.nl"/>
<regex field="destination_number" expression="^illegaleshow$"/>
<action application="set" data="domain_name=illegaleshow.nl"/>
<action application="transfer" data="1200 XML illegaleshow"/>
</condition>
</extension>
You only need to set some DNS SRV records and you're off to go:
_sip._tcp.illegaleshow.nl. 384 IN SRV 10 20 5060 sip.ackspace.nl. _sip._udp.illegaleshow.nl. 384 IN SRV 10 20 5060 sip.ackspace.nl.
Verify that they're active with: dig -t srv _sip._tcp.illegaleshow.nl
dial-string for Skinny and SIP
TODO: SCCP..
command line examples
You can run command line commands either as fs_cli -x "COMMAND" or by running the command line interface fs_cli and typing the COMMAND there
user_exists and user_data
Note that directory users have an id and optionally, a number-alias. Both can be used to register and check if it exists in the directory.
Typical for desk phones:
user_exists id 101 ackspace.nl- true
Typical for soft-phones (SIP client):
user_exists id slackspace ackspace.nl- true
Number from name or number
user_data 101@ackspace.nl attr number-aliasanduser_data slackspace@ackspace.nl attr number-alias- 101
Name from name or number
user_data 101@ackspace.nl attr idanduser_data slackspace@ackspace.nl attr id- slackspace
Group call information:
group_call 100@ackspace.nl- [sip_invite_domain=ackspace.nl,presence_id=slackspace@ackspace.nl]error/user_not_registered,[sip_invite_domain=ackspace.nl,presence_id=hackspace@ackspace.nl]sofia/external/sip:gw+hackspace_at_ackspace@666.666.666.666:5080;transport=udp;gw=hackspace_at_ackspace;fs_nat=yes
Note that for both number and name group calling, you need two identical groups.
dial-string and sofia_contact
There is a user/ endpoint that uses the user's (or more regularly, the directory domain's) dial-string value to lookup the dial string address of the dialed user. This string usually contains the sofia_contact command:
sofia_contact ackspace@ackspace.nl- sofia/external/sip:ackspace@123.456.789.0:9876;transport=udp;user=phone;fs_nat=yes
Note: the contact URI only works on the registered user (use a number instead of a name if the user registered numerically; it happens, see Fritz!Box)
You can call a user by using: originate user/xopr@ackspace.nl 09008002 xml ackspace or originate user/196@ackspace.nl 09008002 xml ackspace.
Also, to inject variables like experimenting with callerid, you can use: originate {caller_id_number=31457112345}user/bergeijk@ackspace.nl xopr xml public
