Freeswitch not accepting incoming SIP call (480 Temporarily Unavailable)

paulw

Hi -

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.

pfSense 1.2.3-RC1
Firewall/WAN
- Pass TCP/UDP 5060-5090
- Pass UDP 16384-65535
FreeSWITCH 0.9.5
- 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
sip:gw+sip.voip.com@111.222.333.444:5080;transport=udp SIP/2.0

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?

Thanks!

Paul

<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.

Thanks to mcrane for his help on IRC.
