When the Hold or Transfer softkey is pressed the call doesn't prompt to enter the destination number. This happens for all phone types. The max calls and busy trigger is 4/2 respectively. Internal call transfer works fine.

Hi Tim,

The only thing that I can think of is that you are running into External Call Transfer Restrictions;

External Call Transfer Restrictions feature allows the Cisco CallManager administrator to configure gateways, trunks, and route patterns as OnNet (internal) or OffNet (external) devices at the system level. By setting the devices as OffNet, administrators can restrict the transferring of an external call to an external device and thus help prevent toll fraud.

From this doc;


Hope this helps! Let us know.

We don't have that enabled. Other sites work fine... it just seems to be this site. The new call line doesn't even appear when the Transfer button is pressed...

I switched to MGCP and it works... could have been something wrong with H323 config.

Anyone know if MGCP in IOS 12.4 allows Caller-ID support? I know in 12.2 it wasn't supported.
