A technique for providing a voice traffic indication in a communication network includes creating a request to set up a communication session in a first network element of the network, the request including a voice traffic indication. The request is then forwarded to a second network element which detects the voice traffic indication in the forwarded request. The second network element then sets up the communication session in response to the request taking into account that voice traffic is to be transferred. The communication channel may include a PDP context. The second network element may be one of an SGSN, a GGSN, or an RNC. The first network element may include an MS.
