Bug: Pua_reginfo
by Gnaneshwar Gatla 08 May '12

Hello all, There seems to be an deadlock between registrar and pua_reginfo module whenever a SIP client refreshes its registration. 1. The pua_reginfo does not publish Event:reg when a sip client registers for the first time. 2. The pua_reginfo module does not use ul.lock_udomain() to lock the ul table to get the record. 3. The pua_reginfo does not release the record that it accessed from ul.get_urecord() Since the record is not released, when the client re-registers, the … [View More]

Re: [SR-Users] Kamailio LDAP integration
by Reda Aouad 07 May '12

Sorry didn't reply to mailing list before. Emails are below. SHA1 encryption may not encrypt the same way as HA1 (HA1 = MD5 of realm + username + password), so the problem may be here. I suggest you store your passwords as clear text in LDAP for testing first.

Remove_hf doesn't work
by Openser Kamailio 07 May '12

07 May '12

Hi, I'm currently working with kamailio 3.2. I try to remove the Contact Header field with remove_hf("Contact") through the file named kamailio.cfg. When i apply remove_hf("Contact"), it only removes the word Contact, but the contact address is still present. Let me show you: Without remove_hf: Contact: sip:<20505@sipserver.com:5060>;......... After remove_hf: sip:<20502@sipserver.com:5060>;............ I want to remove the whole contact address. Thanks for help!
