* '''Remove Comfort Noise (CN) Capability from SDP'''
During the tests we found out some specific 3rd party devices connected to the IMS network when doing the coder negotiation to a single coder preference repeat the coder negotiation till they have only 1 coder in the offer or till they reach a specific number of retries. Since Innovaphone by default always include the payload 13 (Comfort Noise) this would made the remote device to do multiple re-invites to try to reach to a single coder/payload in the offer.
To avoid this we could disable the sending of Comfort Noise capability since this it's not used and by design was implemented for Lync Interop.

Emergency Calls

Extra Options

  • SIP Options Interval (Optional)

The IMS from Proximus uses SIP Options to monitor the SIP Trunks, so it's mandatory that Innovaphone replies to incoming SIP Options received, this it's done by default. Additionally we can also send SIP Options to the SIP Proxy and have similar mechanism for redundancy mechanism, when the remote Proxy doesn't reply to outgoing SIP Options the Innovaphone Gateway will send the call to the next interface.

  • Remove Comfort Noise (CN) Capability from SDP

During the tests we found out some specific 3rd party devices connected to the IMS network when doing the coder negotiation to a single coder preference repeat the coder negotiation till they have only 1 coder in the offer or till they reach a specific number of retries. Since Innovaphone by default always include the payload 13 (Comfort Noise) this would made the remote device to do multiple re-invites to try to reach to a single coder/payload in the offer. To avoid this we could disable the sending of Comfort Noise capability since this it's not used and by design was implemented for Lync Interop.
