Hi, Rajan!!

They're able to hear each other.

The problem occurs just when the call is transfered.

Regards,

Hi Fernando,

In that case, check the region settings configured for the two phones to see whether any difference and try to collect packet captures from the phone where the user is unable to hear to check. Also check whether the subnet the phones are in are allowed RTP communication to the IP address of the PSTN network both ways.

HTH

Rajan

Rajan,

Both phones are using the same region settings. 

Since the extension is allowed to receive calls coming from PSTN, it means the RTP communication is allowed, doesn't it?

hello rajan 

thanks for replying :)

my issue not about hearing its about dialing when i dial any number its not complete the dialing and its back by its self to main display (display name i mean normal )  some times happen with me and come back again by it self ?

maybe sim card or coverage network issue?

dunt know
