[Linphone-developers] standalone cisco 7941

Take care: two language version

V2 = original version in french
===================
V1 = english

On a cisco 7941 I have the good parameters  (file SEP_MAC.cnf.xml ) on a sip account by ippi.fr without a local pbx( or asterisk..), and it's work fine.

Configuration:
eth0             10.42.0.1
7941/eth0    10.42.0.36
wlan 1         10.59.88.147

cisco 7941: firmware SIP version SIP41.8-5-4S

I want to have another type of sip account ( linphone or ekiga ), but there is something wrong somewhere.

In the linphone softphone, the sip accounts linphone or ekiga works fine.

But when put on the cisco 7941 ( via the SEP_MAC.cnf.xml file ) none of linphone or ekiga registrar are responding to the first REGISTER request.

I want to understand the origine of this.

With wireshark : from the linphone softphone with a linphone sip account, the REGISTER REQUEST is the following ( and work fine)


register: softphone linphone // linphone account = OK

But with the cisco 7941, there is no response at all to the following REGISTER request:

I don't find any parameters, in the configuration file of the cisco (SEP_MAC.cnf.xml) allowing a change in that behaviour.

What from the CISCO is facing issue with sip.linphone.org ?
 
It seems that the Call-ID is the origine of the problem, but I haven't found any way of modifying it with the cisco configuration file.


Best regards

V2 = original version in french

Sur un  cisco 7941 et j'ai paramètré ( fichier SEP_MAC.cnf.xml ) un compte sip ippi directement sans PBX, ça marche trés bien.

Configuration:
eth0             10.42.0.1
7941/eth0    10.42.0.36
wlan 1         10.59.88.147

Je cherche à paramètrer un autre type de compte sip linphone ou ekiga de la même façon mais cela ne marche pas.

Dans le softphone linphone les comptes linphone ou ekiga fonctionnent.
Par contre ils ne répondent pas à la requete REGISTER quand elle provient du cisco 7941.

J'aimerai comprendre d'ou vient la différence.

Avec wireshark : une trame issu du softphone linphone avec un compte sip linphone => avec la requete REGISTER donne ceci:


register: softphone linphone // compte linphone  = OK

Par contre une trame issu du cisco à laquelle sip.linphone.org ne répond pas donne cela:

Je ne trouve pas de paramètres qui change ce comportement dans le fichier de configuration du cisco.

à partir du CISCO qu'est-ce qui pose problème à sip.linphone.org ?

Il me semble que le Call-ID pose problème, mais je n'ai trouvé aucune possibilité d'en modifier la valeur sur le cisco.
