IPECS 5.5FC SIP Issues

[mycomms]

Does anyone know if there are any issues with getting Voiceflex SIP trunks to register on the 5.5FC software?
I never had any problems with Voiceflex on phase 5,the only way i could get them to register was to put a DNS address in Pgm 102 but can't get inbound calls

I don´t have Voiceflex sip trunks but since 5.5Fc there are a lof of changed security features.
Two examples:
When IP AUTH USAGE is “ON”,
iPECS respond for below 3 cases otherwise does not reply.
1. INVITE from Proxy server IP or Domain in PGM133.
2. INVITE from registered SIPEXT.
3. INVITE from Branch office.

PGM211 – 407 Authentication : 401/407 is used for SIP REGISTER and INVITE. ID and Password are used for security.
