Hi,
we are trying to register Etisalat SIP via registrar dns:vims-siptrunk.etisalat.ae but getting 401 unauthorized from telco. They are saying we have to send another request with header including domain name, credentials and MD5 encryption. As per Etisalat, we are missing header. any one who did configuration from CUCM > 2900 voice gateway >> Telco ONT >> Telco.
sip-ua
credentials username +97142746222@ims.etisalat.ae password 7 1315062A1209337D6F realm ims.etisalat.ae
