Hello, We are switching from 1.1 to 1.2, and i have some problems. 1) Could you please tell me how should i handle natted contacts in regisers. i read modparam("registrar", "nat_flag", 6) is not exists any more i guess i should use nat_bfalg in usrloc module, but i don't know how to use this, could you tell me an example? how should i set the branch flag which should be used for this? 2) There is no Calling-Station-Id and Called-Station-Id in radius accounting packets. Although i use the same libradiusclient_ng.so, with the same configuration files, and the same radius server too. I need these attributes, could you please tell me why they are missing? Thanks any help, Tamas

[OpenSER-Users] How to decode "methods" field in "location" table?

by Iñaki Baz Castillo

Hi, in case I want to detect which methods allow a registered device I think I should examinate the "methods" field in "location" table, but don't know how to decode it. For example: - 7999 means: INVITE,ACK,BYE,CANCEL,OPTIONS,PRACK,REFER,NOTIFY,SUBSCRIBE,INFO,MESSAGE - 5183 means: ACK,BYE,CANCEL,INFO,INVITE,NOTIFY,OPTIONS,REFER How could I know if a device allow X method? Thanks. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

Re: [OpenSER-Users] Problem with otg proxy when service provider has two registrars

by Robert Dyck

I had already tried configuring the UA with the address of one of the servers ( both IP and domain name ) as well as altering the openser config to force the address. The peculiar thing there is that the registrar does not challenge or even respond at all. It would seem that it ignores REGISTER requests that do not have callcentric.com as the domain name and realm. The UA can register with this provider without difficulty when the UA is configured to use STUN and no outgoing proxy. The UA does not do a second DNS lookup. It simply uses the same address for both requests. When the UA receives the challenge does it not use the received nonce to encrypt its credentials? I have to admit my knowledge of that subject is shakey. And would this not have to be delivered to the same server that sent the nonce?

[OpenSER-Users] Problem with otg proxy when service provider has two registrars

by Robert Dyck

I am experimenting with using openser as the basis for a home telephone system. Openser resides on the same node as my NAT. I have also employed the rtp proxy feature. I have had some success with my setup but recently I encountered a problem registering with a particular service provider. My phones are set up to use openser as an outgoing proxy. They can register with various service providers except one. From tracing the messages I believe I know what is going wrong. The REGISTER is sent to openser which does a DNS lookup. This results in two registrars. Openser picks one and forwards the messages. The registrar issues a challenge as expected which is sent back to the phone. The phone sends its credentials to openser. Openser does another DNS lookup and sends the message to the other registrar. This registrar also issues a challenge. Thus it continues forever with the credentials being sent to the wrong registrar. My question is, how do I get openser to send the credentials to the registrar that is requesting them? Thanks in advance for any advice.

[OpenSER-Users] Stateful matching of all messages within single call leg.

by Alex Balashov

Also, while I appreciate the 'tm' module's ability to catch replies to messages that are part of the same transaction, i.e. t_check_trans(), but does OpenSER provide a way natively to check if messages associated with *any* transaction are part of a particular logical call leg (i.e. dialogue branch tag, Call-ID GUID)? Right now, I am having to hit my database of stored open Call-IDs via avpops to see if this is the case, and that seems ludicruously expensive.

[OpenSER-Users] carrierroute config examples

by Daryl G. Jurbala

The module docs are a bit light for someone who doesn't have much OpenSER experience (like myself). Does anyone have a working config example, including sample DB data? Thanks, Daryl

[Users] AVP management

by Ovidiu Sas

Hi all, There are modules that are using default values for AVPs. What will happen if another module is reusing the same AVP? Or if the AVP is redefined inside the script? Is this completely orthogonal? Should I worry about this while using AVPs? Regards, Ovidiu Sas
