Cannot place calls to external numbers

[Anonymous]

Hi all, One of our locations is having issues placing outgoing calls to external numbers.  The issue happens several times on and off throughout the day, every day.  It lasts for about 20 minutes average before calls can be placed again.  It has been ongoing for a couple of weeks now. Carrier obtained call samples we provided and said that none of them made it to the SIP Gateway that interfaces with our PBX; so basically they said the issue is on our side because they cannot find the calls on the SIP Gateway.  When debugging the unit using Voice Summary I see the call attempting to route out through the SIP Trunk going to the carrier and it gives a "Temporary Failure" message. A debug using Voice Verbose and SIP Stack Messages shows "Temporary Failure", "No available resources on call from 6969 to T10 " and "Call Failed: rejecting with 503, result = 1". What could possibly be going wrong here?  No problems placing calls EXT to EXT or incoming calls. Debug attached. Calling number: 830-775-1272 EXT:6969 Dialed Number: 830-765-4768 Thx.

Aaron,

We receive the invite then we forward the invite to 10.59.26.2 three times out T10, then it times out after 3 seconds because we never receive a 100 TRYING back.  what is 10.59.26.2?

15:04:19.099 SIP.STACK MSG         INVITE sip:7654768@10.59.26.2:5060 SIP/2.0

Can you attach your config?

Also do another call with following debug:

debug sip stack messages

debug sip cldu

debug voice verbose

Thanks,

Mark

10.59.26.2 is the Carrier's SIP Gateway. Config attached.

I may not be able to run the debugs until Monday.

Thank you.

Hi Mark, Here is the debug with the parameters you specified. Calling Number: 830-7765-1272 Ext 6969 Dialed Number: 830-765-4768.  Rings twice then gives a fast busy.  Same errors as before. Thanks.

Aaron,

You need to tell your provider "Spectrum" that they are not responding to our SIP messages.

If you look at debug below we send invite at 9:47:52:472, then we send second INVITE at 52:979 .5 ms later, then we send 3rd invite at 53.986 1.5sec after 2nd. then we time out with our default timer at 3 seconds at 55:482 . call fails so we send back a 503 serv unavail to the local phone which is normal.

So you need to ask them why they aren't responding to our messages? Let me know if you need any further info.

Thank you.  I'll update once I hear back from them.

This is just an educated guess but it looks like you are sending an internal 4 digit extension for your digit out pulse.  Most providers require you to out pulse a 10 digit number assigned to that trunk. You can do a match replace on trunk 10 the same way you have on trunk 4.

It was a challenge getting them to fix it but it did turn out to be something misconfigured on their end. Thank you.

Glad to hear you got it worked out. Thanks for the update!
