Abstract
In an improved method in a control node managing media sessions between nodes in a telecommunication network, exchanging S10 at least one media session description message between two nodes, and determining S20 if the one message comprises at least one option tag, said at least one option tag indicating potential configurations for said media session. Subsequently, comparing S30 the at least one option tag to a set of network supported option tags, said network supported option tags indicating supported configurations for said network, and modifying S40 the media session initiation message based on the comparison.

A method performed by a control node for managing media sessions between nodes in a telecommunication network, the method comprising:
- exchanging a media session description message between two nodes, said media session description message describing a media session to be initiated between those nodes,
- determining if said media session description message comprises at least one option tag that indicates extensions supporting potential configurations for said media session;
- comparing said at least one option tag to a set of network supported option tags, said network supported option tags indicating supported extensions for said network;
- and
- modifying said media session description message based on said comparison.
A control node configured to manage media sessions between nodes in a telecommunication network, the control node comprising:
- a message managing unit configured to manage a media session description message exchanged between two nodes, said media session description message describing a media session to be initiated between those nodes,
- a message inspection unit configured to determine if said media session description message comprises at least one option tag that indicates extensions supporting potential configurations for said media session;
- a comparing unit configured to compare said at least one option tag to a set of network supported option tags, said network supported option tags indicating supported extensions for said network;
- and
- a message modifying unit configured to modify said media session description message based on said comparison.
