Hello ! 

Using Snom 720 with Freepbx 13. 

I'm facing a problem when picking up a call from blf or with feature code ** the displayed caller ID won't change to the outside caller ID . 
I'm using snom 720 phones and I've setup trustrpid=yes and sendrpid=pai
so the scenario is as follows : 
1. a call rings in ext a (412)
2. ext b picks up (**412) 
3. ext b's display shows the right caller id and then instantly switches the caller id to the name and number of ext a (e.g. Simon 412)

I've also tried setting =>advance settings => sendrpid=pia / yes in advanced settings 
+ I've also tried adding : 
trustrpid=yes
sendrpid=pia
in 
sip_general_custom.conf

any input / Help is much appreciated.

Hi, 
I'm using 

snom720-SIP 8.7.3.25.5

is this version affected by the bug you're describing ? 

Which version is working properly ? 

Thank you . 

Also does this affect 821's firmware ? 

just tried this with 2 snom 821

downgraded to fw 

snom821-SIP 8.7.3.10

same behavior, caller id shows the outside cid briefly and then Extension number + names comes up instead. 

Thanks for any help.
