Solved Not able to connect particular number

[Brock_4118]

Hi Team,
I am unable to make calls within my country itself, it say calls cant be connected contact your administrator,
before we were able to make calls but just last 1 week i am facing this issue.
I don't know whats the cause & i haven't done any changes also.
I ma using 3CX version 15.0.0

What do your logs say? These should give a reason for why the calls failing.

I would PCAP the Call and see whether this response is coming from the PBX or trunk provider, 1 or 2 legs should denote this in the Wireshark trace basically.

Logs are a good idea in certain cases (for example if it is a 3CX outbound rule issue).

... and for the love of God and Country, upgrade to v16.
15.0.0 is quite old now.

Could it be that your provider has changed the required number format for national calls?

Hi Craigreilly
Thanks for your suggestion but i am totally newbie at 3cx & don't know much & our company's whole communication depends on this 3cx so if i will go with upgradation & something will go wrong all the work will hamper that's why i didn't upgrade.
Now this what i see in Dashboard when i make the call
Call or Registration to 1168136666@(Ln.10001@TTSL-66826682) has failed. 0.0.0.0 replied: 503 Service Unavailable; from IP:00.0.00.0:5060
Even if i put 0 it doesn't connect neither with +91
But with the same area code i was able to make call but not that particular number.
I have checked in block list also no any number there.

If some calls go through, this would suggest that your provider is blocking some calls for a reason. Contact them, provide the numbers that work, and those that don't. They should be able to explain what is happening. It may be the number format, calls to high value numbers (mobiles?), or different caller ID being sent.

Hi Leejor,
Finally i can make calls to that particular number now. The issue was actually from my provide side.
After following the issue with them a lot they were able to solve the problem.
& the culprit was codec. just coz of codec i wasn't able to make call to that particular number.
Thanks to everyone for your guidance & help really appreciate alot cheers.
