3rd party Phone and Softphone issues

[AndyKu]

Hi There

trust everyone is well?

i have an issue whereby a client has opted to go the softphone route (3rd party - Microsip)
open sip licenses have been installed and the phones register and can recieve and make calls accordingly with voice quality been 100%

The problem however is that transferring calls does not work, picking up calls in a group does not work and lastly, if the SIP extension is dynamically routed to a hunt group after a certain period or with when ringing the hunt group directly... the SIP extensions dont ringl calling them individually there is no issue.

we have also tried registring a Yealink for example, and we get the very same result.
i have also tried changing the dtmf dynamic payload to a varying number of values and still no joy

The client is running the latest / last release of version 10 R103_064

Please note: the current Alcatel IP phones that are installed work 100%... its just the 3rd party phones and softphones that are doing this.

Please help, as i have registered softphones many times before and have never experienced this.

Regards
Andy

Hi Andy,

Maybe your SIP Phones are not compatible with the OXO. See attached file, you might try with an Polycom IP670 that is validated
