Inbound calls fail with SIP error 408 (Request Timeout):Ĭheck the inbound number is mapped in the system correctly, if necessary the SIP trunk on the portal can be configured to strip the plus, e.g. 8000/20i - 8000Hz at 20ms) cannot interwork with 16000/30i - 16000Hz at 30ms) the call will fail and the codecs in the SIP trunk configuration need to be aligned to use one of the above codecs. If a codec is defined in Asterisk that is not one of the above, or is offering a differing sample rate or interval rate (e.g. Outbound calls fail with SIP error 488 (Not Accepted Here) or I-SUP errors 58 (bearer capability not available) or 88 (incompatible destination):Ĭheck the codecs allowed in the SIP trunk configuration above, VoiceHost only supports: alaw, ulaw, gsm Just because a trunk is showing as registered does not mean it will authenticate correctly. This error most commonly occurs when the call is not authenticating properly, at which point check the above in the SIP trunk configuration (If Asterisk, swap username= for defaultuser= to see if this solves the issue. This is the default configuration of Asterisk regardless of the actual error generated (which is infuriating when you are trying to diagnose the real problem) unless PBX is updated to send back the real error rather than the changed error. Outbound calls error with "all circuits busy" or "congestion": ![]() Given an SRV record of _sip._ pointing to port 5060, Ring makes a connection to and passes all information with domain Here is a trace. The codepath to make the SIP connection as described above already exists - its just that its impossible to configure the UI currently to trigger it. The "domain/hostname" config value would replace the current "hostname" config value. The server to physically connect to is configurable either by DNS record on the domain, OR by explicit configuration in the proxy field. That way the auth information is completely configurable (username + domain) and the server that handles the request is completely configurable (proxy). Lastly, if the DNS SRV record does not exist, Ring attempts to connect to the A record of the domain/hostname setting, and again passes to it. If proxy is not set, then Ring looks for the proxy in the DNS SRV records for domain and if it exists, Ring connects to it and then passes to it. If proxy is set, Ring connects to the proxy and then passes in the SIP header. The way I think it should work (and the way I think Zoiper works) is that you have a "domain/hostname" setting and a "proxy" setting. Explicitly providing the proxy does not work as shown above. IF the system is configured with _sip._udp SRV records on the domain provided in the hostname to point to the proxy, and the proxy field is left blank, then Ring successfully looks up the SRV record and connects to the proxy given there.
