Call Tranfer problem

[kong_cisco1]

Hi,

I have user having problem with the call transfer. When call come in either from Internal or External; after user pick up the call and try to press "transfr" softkey, it just not doing anything. User is using Extension Mobility.

Any suggestion where would be the problem lies from?

Cisco IP Phone 7941G

CCM version 4.2 (1)

Does this works internally?

Or only for PSTN calls?

Which type of GW you are using? H323...?

Using MTP?

Let us know

[kong_cisco1]

It doesnt work when PSTN calls in. Internal call is working fine. The GW is running on H.323

It is not using MTP.. I am wonder if the GW is checked for MTP and No MTP available, will that causing the supplementary services feature?

Thanks

By default yes,it will cause a failure invoking ss.When MTP is enabled, and no MTP can be allocated, CCM will try to connect the call, but no supplementary services will be allocated (can be modified via Service Parameters)

Thanks. is all working now..

The problem is due to the MTP that has checked in the GW config which the service is not using MTP for supplementary services.
