The Northern Ireland skipper, 27, says he wants to stay at the club for the rest of his career.
The ex-Sheffield Wednesday man, a £3million buy in August 2007, said: "It's so important to get people like James and Jonas on new contracts.
"They have been big players in the success we've had here and it is right to see them rewarded.
"It's important to have a core who have been here a long time because they understand the place and have a special feel for the club.
"Having players like that around gives the club an identity.
"Speaking for myself, having that affinity with the club is really nice and I'd love to be able to carry that on here for a long time to come, seeing as we're discussing contracts!"
