Re: [SR-Users] Strange PUA Behaviour

Below is the relevant presence/pua stuff. Let me know if I should be examining other tables. When the call ends, there are no dialogs remaining in the dialog table. A few things do hang around in the presentity and pua tables for a short period of time. Regarding CLI changing, it does seem to do so. When the call is routed onto the billing platform, the CLI is changed to the local “extension” (e.g. 9989) on the leg that comes back to Kamailio, destined for the callee. Regarding only advertising the leg going to the callee, not all calls will terminate on a UA registered against Kamailio (e.g. calls from a Kamailio registered UA to the PSTN). The more I think about it, determining the correct leg in all scenarios will be difficult. mysql> SELECT * FROM presentity\G *************************** 1. row *************************** id: 1 username: 441164969989 domain: 185.28.212.118 event: dialog etag: a.1453224139.18802.144.0 expires: 1453226868 received_time: 1453226743 body: <?xml version="1.0"?> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="0" state="full" entity="sip:441164969989@185.28.212.118"> <dialog id=&quot;b2d95153-ea311679-84b889bb(a)172.31.17.81&quot;

I would only advertise the dialog info states for the call leg going to callee, because it is the one for call pickup. On the other hand for shared line appearance, the caller is watched as well. Is the caller id changed in the middle? Cheers, Daniel On 19/01/16 11:25, Phil Lavin wrote: Hi Daniel, The multiple records are because we are routing calls between UAs which are both registered against Kamailio via an external SIP server (our billing engine). That is causing there to be 2 dialogs created. We have put in a quick hack to not call dlg_manage() when the $fU is “9989”. This does not create 2 records in the dialogs table and the BLF functionality works as expected. What do you propose as the correct fix for this situation?
