Freeswitch not accepting incoming SIP call (480 Temporarily Unavailable)
Over the weekend I installed FreeSWITCH on an existing 1.2.3-RC1 system. I am able to register with my SIP provider and make outgoing calls, but cannot receive incoming calls. Here is my setup.
- Pass TCP/UDP 5060-5090
- Pass UDP 16384-65535
- Bound to WAN adapter
- Gateway to SIP provider (registers OK)
- Extension 100 can make outgoing calls OK
- Public dialplan
. 100, enabled, order 000
. condition destination_number ^(my_phone_number)$ order 000
. action transfer 100 XML default order 000
So, I thought I would monitor traffic on the WAN interface with packet capture. I can see the invite from my SIP provider, followed by a "trying" response from FreeSWITCH, but FreeSWITCH sends a "temporarily unavailable" message back to my SIP provider.
SIP_PROVIDER > FreeSWITCH Request-Line: INVITE
FreeSWITCH > SIP_PROVIDER Status-Line: SIP/2.0 100 Trying
FreeSWITCH > SIP_PROVIDER Status-Line: SIP/2.0 480 Temporarily Unavailable
The reason in the last line is reported as "Reason: Q.850;cause=16;text="NORMAL_CLEARING"", though I'm not sure if this is very helpful.
Any ideas on what I'm missing here, to accept incoming calls?
<sigh>responding to my own post. On the public dialplan, I inadvertently placed 1 before my sip phone number. Correcting this allowed me to accept incoming calls.
After fixing this, I found that the IVR voice messages via my SIP provider were choppy, as a result of a transcoding error. Updating my external profile with the following fixed this.
