Version 20 upgrade issue - no call transfer.

[jwt0992]

Since the upgrade to version 20 from 18 we no longer can transfer internally or externally to a cell number. I have checked for issues with the SIP provider (Charter/Spectrum/Time Warner) which had none. We have looked at every post and tried all of the solutions provided. The log states a warning for an event ID 12294 Call or Registration to 5555555555@(Ln.10001@Spectrum) has failed. sip:x.x.x.x:5060;lr replied: Forbidden (403) and the caller here a message that the "Transfer Failed". Firewall setup is correct as per the dashboard. The outbound rules have not changed from 18.

12294

Call or Registration to %1 has failed. %2 replied: %3

Warning

Check the reply from the endpoint.

Hi,

Do a packet capture and let us see what gets sent out, and what the response from endpoint actually is.

Im sure there were a load of threads like this way back when v20 came out.. wasnt it down to roles?

have you assigned roles to your users and check they have permissions set?

or maybe it was not assigning departments?

Users have roles and there is a default department.

Further down the rabbit hole. This has everything to do with caller ID and what Spectrum is expecting to see.
