SIP client not forwarding calls

[m33k333]

I'm using a VOIP number acquired through JMP.chat and have configured all the settings correctly via a SIP client channel. When I test it, I hear a "call cannot be completed at this time" recording and then it drops. Is there a status page or another way to check whether the number has been successfully registered and troubleshoot the issue? I've tried entering information I know is incorrect and Verboice gives the same message every time - "Channel [channel name] has been successfully updated".
Any thoughts? Thank you!

^ What is meant by "configuration number provided by SIP provider"? I assumed this is the phone number but the example screencap has a 4 digit number.

Adding some more contextual info to the original post in the hope that it helps troubleshooting:

• JMP.chat support confirms @m33k333 's settings are correct. The only thing they could think of is that the "number" field should be the port # [5008] instead of the phone #. @m33k333 tried that and it still doesn't work. They've also tried adding ":5008" to the end of the domain to no avail.

Here's a (redacted for privacy) screenshot of @m33k333's config:

Hi @m33k333!

Sorry to hear about the issues you're facing.

The number is indeed the phone number your provider assigns you. I can't open the link you shared, but there's a chance they were testing with a provider like CallCentric that allows you to use short phone numbers (the extension number, instead of the full number).

I really don't know what's going on, and troubleshooting SIP calls is a bit tough. I can offer you to schedule some time for you to test a few calls while we log the SIP message exchange between Verboice and your provider - and maybe the provider's support can help you identify the issue once they have the logs?

If that works for you, ping me at mgarcia [ at ] instedd [ dot ] org
