Hi, Can some one help?
MXE II, MCD 5.0 SP 1. PR1, SIP Trunk License, also have MBG Virtual with SIP Proxy, but this has been removed from the application until we can sort the problems out.
We are trying to install SIP Trunks for a customer in New Zealand using Telstra NZ, but are having problems with no audio.
At present we are using our test lap system to set this up.
Now to explain fuller, Incoming calls OK, transfer OK, Conference OK, Outgoing call from a 5212 & 5312 no audio, Outgoing call from a 5320 OK.
Also to confuse, sometimes after an incoming call to a 5212(successful) you can then call out from that 5212 ( successful).
Is there a problem (programmable option) associated with the 5212 &5312? with SIP Trunks.
Because Telstra NZ's SIP Trunks have not been certified by Mitel ( who want us to do the certification) Mitel will only help if we pay.
Any help, ideas?
Regards
Dave
