SIP Notify: remote and local tag containing the same extension

Hello,

First of all my Setup is:

Asterisk Version: 13.9.1
FreePBX Version: 13.0.188.9
chan_sip for the extensions

Since I’m having huge problems with the BLF feature of yealink phones, I digged through many logfiles and found the following SIP Notify Body: ("<" was removed, due to quote feature)

remote>
identity display=“605”>sip:605@192.168.YY.YY:5160
target uri=“sip:605@192.168.YY.YY:5160”/>
/remote>
local>
identity display=“605”>sip:605@192.168.YY.YY:5160
target uri=“sip:605@192.168.YY.YY:5160”/>
/local>

Thus, resulting in the Phone showing “605 is calling 605”. How can I solve this problem ?

There is an option issue[1] for this problem.

Yeah, I’ve also found that, but its from 2014 and still not solved.
I need some workaround though, because it’s not possible to deploy the new PBX without this feature.

If there were any workaround or fix it would be on the issue, unless someone has come up with one and not shared it.
