Asterisk Team commented on ASTERISK-28739:
------------------------------------------

Thanks for creating a report! The issue has entered the triage process. That means the issue will wait in this status until a Bug Marshal has an opportunity to review the issue. Once the issue has been reviewed you will receive comments regarding the next steps towards resolution.

A good first step is for you to review the [Asterisk Issue Guidelines|https://wiki.asterisk.org/wiki/display/AST/Asterisk+Issue+Guidelines] if you haven't already. The guidelines detail what is expected from an Asterisk issue report.

Then, if you are submitting a patch, please review the [Patch Contribution Process|https://wiki.asterisk.org/wiki/display/AST/Patch+Contribution+Process].

Please note that once your issue enters an open state it has been accepted. As Asterisk is an open source project there is no guarantee or timeframe on when your issue will be looked into. If you need expedient resolution you will need to find and pay a suitable developer. Asking for an update on your issue will not yield any progress on it and will not result in a response. All updates are posted to the issue when they occur.

> We are seeing a "Dropping redundant connected line update" message in the Asterisk log which appears to be incorrect.
> The channel with the update is created by a Dial out from Asterisk to a SIP telephone:
> [Feb 13 14:05:01] DEBUG[2899] manager.c: Examining AMI event:
> Event: Newexten
> Privilege: call,all

> CallerIDNum: 897
> CallerIDName: John

> Extension: 171373917
> Application: AppDial
> AppData: (Outgoing Line)
> This results in an INVITE:
> [Feb 13 14:05:01] VERBOSE[23326][C-0000019a] chan_sip.c: Reliably Transmitting (NAT) to AAA.AAA.52.245:5060:

> Via: SIP/2.0/UDP AAA.AAA.52.245:5070;branch=z9hG4bK76f896c2;rport

> Call-ID: 2baf801c5631714d53c92b27735249a6 at AAA.AAA.52.245:5070
> Later we try to update the callerid to 0123456789 via the AMI however Asterisk rejects it:
> [Feb 13 14:05:07] DEBUG[23424] manager.c: Running action 'Login'
> [Feb 13 14:05:07] DEBUG[23424] manager.c: Running action 'Setvar'
> [Feb 13 14:05:07] DEBUG[23424] channel.c: SIP/AAA.AAA.52.245:5060-000002f0: Dropping redundant connected line update "0123456789" <0123456789>.
> [Feb 13 14:05:07] DEBUG[23424] manager.c: Running action 'Logoff'
> Reading the Asterisk code, I believe it should only be considered redundant if the callerid is unchanged, but here it really is different.
> Please let us know what else is needed to debug this issue. Thank you.
