Re: Inbound calls to derived direct routing trunk fails with 404
Thanks for the reply. I found the problem and it was that I used the carrier domain teams1.example.com / teams2.example.com as domains in the record route headers. Changing to using the customer tenants sbc-domain (sub-domain) customer1.teams1.example.com / customer1.teams2.example.com in the record route headers made it work. I thought that the Contact header was the important one. But apparently not5.6KViews0likes0CommentsInbound calls to derived direct routing trunk fails with 404
I'm working on setting up a multi-tenant SBC but I can't get inbound calls to work (inbound to Teams). Domains: teams1.example.com - This i registered in the Carrier tenant teams2.example.com - This is registered in the Carrier tenant customer1.teams1.example.com - This is registered in the customers tenant customer1.teams2.example.com - This is registered in the customers tenant I have successfully registered all the domains and validated them by adding temporary users with phone licenses, I have setup two OnlinePstnGateways in the carrier tenant, SIP Options works in both ways and it looks good in the teams admin console. get-csOnlinePstnGateway Identity : teams1.example.com InboundTeamsNumberTranslationRules : {} InboundPstnNumberTranslationRules : {} OutboundTeamsNumberTranslationRules : {} OutboundPstnNumberTranslationRules : {} Fqdn : teams1.example.com SipSignalingPort : 5061 FailoverTimeSeconds : 10 ForwardCallHistory : True ForwardPai : True SendSipOptions : True MaxConcurrentSessions : 500 Enabled : True MediaBypass : False GatewaySiteId : GatewaySiteLbrEnabled : False GatewayLbrEnabledUserOverride : False FailoverResponseCodes : 408,503,504 PidfLoSupported : False MediaRelayRoutingLocationOverride : ProxySbc : BypassMode : None Description : Identity : teams2.example.com InboundTeamsNumberTranslationRules : {} InboundPstnNumberTranslationRules : {} OutboundTeamsNumberTranslationRules : {} OutboundPstnNumberTranslationRules : {} Fqdn : teams2.example.com SipSignalingPort : 5061 FailoverTimeSeconds : 10 ForwardCallHistory : True ForwardPai : True SendSipOptions : True MaxConcurrentSessions : 500 Enabled : True MediaBypass : False GatewaySiteId : GatewaySiteLbrEnabled : False GatewayLbrEnabledUserOverride : False FailoverResponseCodes : 408,503,504 PidfLoSupported : False MediaRelayRoutingLocationOverride : ProxySbc : BypassMode : None Description : In the customers tenant I have done the following Set-CsOnlinePstnUsage -Identity Global -Usage @{Add="Example"} New-CsOnlineVoiceRoute -id "ExampleVoiceRoute" -NumberPattern ".*" -OnlinePstnGatewayList @{add="customer1.teams1.example.com"} -OnlinePstnUsages Example Set-CsOnlineVoiceRoute -id "ExampleVoiceRoute" -OnlinePstnGatewayList @{add="customer1.teams2.example.com"} New-CsOnlineVoiceRoutingPolicy "ExampleVoiceRoutingPolicy" -OnlinePstnUsages "Example" Set-CsPhoneNumberAssignment -Identity "the-user@customer-domain.com" -PhoneNumber "+4611111111" -PhoneNumberType DirectRouting Grant-CsOnlineVoiceRoutingPolicy -Identity the-user@customer-domain.com -PolicyName ExampleVoiceRoutingPolicy And that worked. I can make outbound calls (from Teams to PSTN) via the derived trunk. But when I try to make a call to Teams I get the the following 404 Not found back SIP/2.0 404 Not Found REASON: Q.850;cause=1;text="some-uuid;RNL" INVITE sip:+4611111111@sip.pstnhub.microsoft.com:5061;transport=tls;user=phone SIP/2.0 Record-Route: <sip:teams1.example.com;transport=tls;r2=on;ftag=tsipTsQXP39y0q2RVS;lr> Record-Route: <sip:teams1.example.com;transport=udp;r2=on;ftag=tsipTsQXP39y0q2RVS;lr> Call-ID: 83f1c358adaf4296d60a2056eaf439dd CSeq: 1 INVITE From: <sip:+468888888@customer1.teams1.example.com:5060>;tag=tsipTsQXP39y0q2RVS To: <sip:+4611111111@sip.pstnhub.microsoft.com:5061;transport=tls;user=phone> Via: SIP/2.0/TLS IP_OF_SBC:5061;branch=z9hG4bKf0d8.3861ded29751ad19ec28cfbfa6db9770.0 Via: SIP/2.0/UDP IP_OF_OTHER_SERVICE:5060;rport=5060;branch=z9hG4bK-373238-b364b879dd564de5c745b3c199a0aefd Max-Forwards: 69 Record-Route: <sip:IP_OF_OTHER_SERVICE;lr> Content-Type: application/sdp Supported: 100rel,replaces Allow: ACK,INVITE,BYE,CANCEL,PRACK,UPDATE,REFER Content-Length: 325 Contact: <sip:+468888888@customer1.teams1.example.com:5061;transport=tls> SDP..
