I'm trying to call a number in Germany. When i used manual dial from the agent screen i can dial this number without problems. When i place this number in a list and use autodial it fails. I tried two different SIP providers.

I have enabled sip debug and looked up the ID of the call in asterisk/messages. I used grep to filter like this:

Code: Select all

grep "C-00000075" /var/log/asterisk/messages

I then placed the output in two text files and used Winmerge to compare the calls.

The only differences i noticed:

On the manual dial call the AGI command is:

Code: Select all

AGI("Local/8600051@default-00000058;1"

And on the auto dial call the AGI command is:

Code: Select all

AGI("Local/5491805309000@default-0000005a;2"

And then eventually the autodial call fails with:

Code: Select all

chan_sip.c: Got SIP response 486 "Busy Here" back from <IP redacted>
app_dial.c: SIP/cmcom-0000004b is busy
app_dial.c: Everyone is busy/congested at this time (1:1/0/0)

What could be causing the autodial call to fail here?

CallerID is different with Autodial vs Manual dial. Dead giveaway if a carrier is averse to Dialers. Not sure about the Caller ID Name value in that country, but the entire caller ID is different, number and name, Auto vs Manual.

Yes, i was suspecting the caller ID as the culprit. But i suppose only the SIP provider can see how the caller ID is formatted and why it is being rejected?

Any tips on how i can further resolve this issue from within vicidial?

YOU can view the CID information in the INVITE packet using sip debug. But the rejection reasoning is a code/text response and has no real rule set. If they share anything more than "Busy Here" and a code (which likely translates to Busy Here) I'd be surprised. But often the sip debug packet information is ... informative and may show more differences than you suspect. A digit out of place ...

Autodial call:

Code: Select all

From: "V2172259030000001010" <sip:<number redacted>@<ip redacted>;tag=as51bb1332

Manual dial call:

Code: Select all

From: "M2172257440000001476" <sip:<number redacted>@<ip redacted>;tag=as3ba047d8
