What steps will reproduce the problem? 1.Set up an audio session from imsdroid and capture the INVITE 2.Look at Contact and Accept-contact header 3.

What is the expected output? What do you see instead?

This is how the MMTel ICS looks in the capture: +g.3gpp.icsi-ref="urn%3Aurn-7%3gpp-service.ims.icsi.mmtel" The second colon has not been escaped correctly, 3A is missing. It should look like this: +g.3gpp.icsi-ref="urn%3Aurn-7%3A3gpp-service.ims.icsi.mmtel"

What version of the product are you using? On what operating system?

Please provide any additional information below.
