Hoping someone can give me some ideas. I just configured a FreePBX system, and would like to use the FindMe/FollowMe feature to send calls to cell phones. I have done this many times before without issue, but something is not right in this instance. Whenever I call from one extension to another extension that has FM/FM enabled, i get reorder tone, and the error on the console as follows:

Reading the other posts about this error has not been very helpful as they all seem to reference SIP or PJSIP channels, and not the Local channel.
Reading the error, it appears that the Local channel does not have a codec assigned so it cannot translate the call???
IF i call into the system from the outside, and dial the extension, then the call follows the followme just fine. The issue is only when making the call from an internal extension.
We have a new FreePBX installation and FindMeFollowMe does not work with the same error. Weāve also tried a custom extension dialing the outside number, adding the extension in the FindMeFollowMe instead of the outside number didnāt work either ā same error as above.
Does anyone have any ideas on this? This is an instance on AWS, so not sure that that would make any difference. The find-me-follow-me is a pretty critical feature and even trying to create a custom extension that dials the outbound number and adding just that extension on the find-me-follow-me breaks with the same error.
There is currently a patch up for Asterisk[1] which would probably resolve the issue. Itās not going to make this current release, but next one so probably 6-8 weeks out. If you provide a SIP trace of the calling party then it may be possible to confirm if the patch would fix it.
Iāve built Asterisk from scratch with that patch and can confirm that this fixes the issue. The FMFM is a pretty major feature ā I hope that you might have a patch out sooner than 5 or 6 weeks.
The patch is in the Asterisk source code for the next set of releases. We donāt cut one off releases for stuff like this, and the issue itself has been in the tree for a few months at this point so itās not a recent regression. FreePBX could pull in the fix if they wanted, but I donāt manage that project. It also doesnāt impact a large number of users. It requires a particular scenario to occur.
The particular scenario is with a device offering multiple audio streams. We accept only one, and the rest are removed/rejected streams.
According to the JIRA issue[1]ā¦ the functionality which introduced this issue was released in 16.12.0, 17.6.0, and 18.0.0 so anything before those would be fine.
