Retransmission timeout reached - What is this error?

Postby macaruchi » Mon Aug 22, 2022 2:40 pm

Hi!
I am using a GoIP GSM gateway with my Vici server for now they are working with outbound calls so fine my problem is when I try to use them with inbound calls for these GSM chips.
When I call to these numbers from gsm gw the call arrives to asteriks,because I see in the console, but never comes to in-group and voicemail of the number go in.

Bro,
The error and documentation is literally in there:
https://wiki.asterisk.org/wiki/display/ ... nsmissions
There is no reply to SIP retransmits from your remote device, indicating a network/firewall/device issue.
