I have a problem with some phone numbers at Telenor. Our door telephone does not reply with an ACK on the 200 OK.

All I found was a weird SDP response with two "connection information" lines

Session Description Protocol

    Session Description Protocol Version (v): 0

    Owner/Creator, Session Id (o): BroadWorks 307119541 1 IN IP4 194.247.61.31

    Session Name (s): -

    Connection Information (c): IN IP4 194.247.61.31

    Time Description, active time (t): 0 0

    Session Attribute (a): sendrecv

    Media Description, name and address (m): audio 23116 RTP/AVP 8 101

    Connection Information (c): IN IP4 194.247.61.31

    Media Attribute (a): rtpmap:8 PCMA/8000

    Media Attribute (a): rtpmap:101 telephone-event/8000

    Media Attribute (a): fmtp:101 0-15

    Media Attribute (a): maxptime:40

    Media Attribute (a): bsoft:1 image udptl t38

    Media Attribute (a): sendrecv

    Media Attribute (a): silenceSupp:off - - - -

    Media Attribute (a): setup:actpass

To debug, I would like to remove one of the "Connection Information (c): IN IP4 194.247.61.31", to see if this is what confuses the door telephone.

But how do I do that?

I tried with this but nothing happeded

onreply_route[DOOR_MANAGE_REPLY] {

        if (is_method("INVITE|SUBSCRIBE"))

        {

          sdp_remove_line_by_prefix("c=IN IP4 194");

        }

        return 1;

}
