Hello. I`am doing external calls via sip provider. And I have internal SIP server (opensips) with users. My case: two my users connecting via my sip server. One of him starting conference and calling to external number (carrier number or mobile phone). But when I doing call to external number, I got error 488 INCOMPATIBLE_DESTINATION on call. For setup I done next steps: 1) create file /etc/freeswitch/sip_profiles/external/freelycall.com.xml with provider-access params 2) set dialplan extension with my mobile number (hardcoded expression for testing) <extension name="outbound_calls_to_freelycall"> <condition field="destination_number" expression="^(7906*******)$" break="on-true"> <action application="set" data="hangup_after_bridge=true"/> <action application="bridge" data="sofia/gateway/freelycall.com/$1"/> </condition> </extension> 3) set default provider params and external hosts in vars.xml <X-PRE-PROCESS cmd="set" data="external_rtp_ip=host:freelycall.com"/> <X-PRE-PROCESS cmd="set" data="external_sip_ip=host:freelycall.com"/> ... <X-PRE-PROCESS cmd="set" data="default_provider=freelycall.com"/> <X-PRE-PROCESS cmd="set" data="default_provider_username=MY_ID"/> <X-PRE-PROCESS cmd="set" data="default_provider_password=MY_PASS"/> <X-PRE-PROCESS cmd="set" data="default_provider_from_domain=freelycall.com "/> <!-- true or false --> <X-PRE-PROCESS cmd="set" data="default_provider_register=true"/> <X-PRE-PROCESS cmd="set" data="default_provider_contact=5000"/> I starting debug: freeswitch -c command "sofia status" say: Name Type Data State ================================================================================================= 172.31.22.124 alias internal ALIASED external profile sip:mod_sofia@172.31.22.124:5060 RUNNING (0) external profile sip:mod_sofia@172.31.22.124:5061 RUNNING (0) (TLS) external::freelycall.com gateway sip:MY_ID@freelycall.com REGED internal profile sip:mod_sofia@172.31.22.124:5080 RUNNING (0) internal profile sip:mod_sofia@172.31.22.124:5081 RUNNING (0) (TLS) ================================================================================================= 2 profiles 1 alias Thats good I think. command "sofia status profile external" say: ================================================================================================= Name external Domain Name N/A Auto-NAT false DBName sofia_reg_external Pres Hosts Dialplan XML Context public Challenge Realm auto_to RTP-IP 172.31.22.124 SIP-IP 172.31.22.124 URL sip:mod_sofia@172.31.22.124:5060 BIND-URL sip:mod_sofia@172.31.22.124:5060;transport=udp,tcp TLS-URL sip:mod_sofia@172.31.22.124:5061 TLS-BIND-URL sips:mod_sofia@172.31.22.124:5061;transport=tls HOLD-MUSIC local_stream://moh OUTBOUND-PROXY N/A CODECS IN GSM CODECS OUT GSM TEL-EVENT 101 DTMF-MODE rfc2833 CNG 13 SESSION-TO 0 MAX-DIALOG 0 NOMEDIA false LATE-NEG true PROXY-MEDIA false ZRTP-PASSTHRU true AGGRESSIVENAT false CALLS-IN 0 FAILED-CALLS-IN 0 CALLS-OUT 0 FAILED-CALLS-OUT 0 REGISTRATIONS 0 I`am not sure, that all correct, but I don`t know how should look like the right output of this command When I starting call, I see next row in log: 2016-04-07 07:52:09.195582 [NOTICE] switch_ivr.c:2092 Transfer sofia/external/8@MY_OPENSIPS_DOMAIN to XML[7906*******@default] I think, that @default is incorrect, I think that domain should be look like as @freelycall.com What I doing incorrect?
