Max Inbound Calls?

[IanGP]

Hi Everyone,

VERSION: 2.14-740a
BUILD: 200315-1126
Asterisk 13.29.2-vici

We have an inbound call centre that's taking about 11k calls per day, 92% of which are handled by IVR.
So at any given time, there are max 15 agents taking calls.

However, some calls are not getting through to Vicidial.

tcpdump shows me that the voice provider is trying to send the call, but we see either:

Code: Select all

SIP: SIP/2.0 401 Unauthorized

Or

Code: Select all

SIP/2.0 403 Forbidden

Edit: Inbound with this provider does not require authentication

Is this perhaps because my system can't handle the volume?
Is there a way to increase concurrent inbound calls on Vicidial?

TIA
IanGP

Just the error message without full debug from start to finish is not enough to troubleshoot a problem such as this. Often unauthorized is merely a prompt to send credentials. Forbidden on inbound would be something you send to them and obviously shouldn't happen. Full asterisk cli output from a single example would provide much more information and make it possible to begin troubleshooting. However: Do not post 3000 lines of unrelated calls. Try to have NO other traffic on the system (if feasible) during the test call so all cli output is for this one test call. Consider including the carrier context as well, blotting out any senstive information such as IPs, users, and passwords.
