Hello everyone. I allow myself to submit a problem that I can not solve with my VOIP
provider Orange in France

[2023-06-08 13:19:03] ERROR[185091]:
res_pjsip/pjsip_configuration.c:1044 from_user_handler: Error configuring endpoint ‘Biv_Sortie’ – ‘from_user’ field contains invalid character ‘@’

Question how can I solve this character problem “@”?

2) resolution of the orange-obs.fr DNS.  I am attaching an extract from the documentation that Orange issued in 2015

SIP/Internet is described in RFC3261 and following. THE
SIP/IMS is described by 3GPP standards. It’s not the same SIP. In the Internet world, VoIP machines route SIP messages to the IP addresses of the FQDNs of the SIP URIs
(VoIP domain). In the 3GPP world, SIP messages are routed to an I/P-CSCF (depending on whether we are in interco or in IPBX) which has a different FQDN from the VoIP domain.

BIV SIP

– P-CSCF FQDN: pcscfgm.orange-obs.fr, resolved by DNS
voice
– VoIP domain: orange-obs.fr, not resolved by voice DNS. ex :
INVITE sip:0142277620@orange-obs.fr SIP/2.0
2
 The VoIP/Internet machine will not be able to determine the address recipient of SIP messages.

run the command “nslookup pcscfgm.orange-obs.fr” and note the returned IP address 217.167.210.X
– add this address in the /etc/hosts file of the PBX:
217.167.210.X pcscfgm.orange-obs.fr orange-obs.fr

Note that it works with sip.conf . The current installation is operational with the information provided by /etc/hosts

Do you have an idea of what I can do to make this new installation operational?

thank you in advance.
