Re: [Users] question about ACK

23 Apr 2007

User-Agent: Brcm-Callctrl/v1.7.1.1 MxSF/v3.6.2.5. is buggy

The request URI of the ACK should be the Contact URI of the 200 Ok.

regards
klaus

  Hello all,

 In the following call to PSTN, Openser gets into an infinite loop when
 the ACK is received. It starts sending the ACK to itself. Is this
 because the ACK is not right or could it be a misconfiguration in my
 part?

 thank you for any help

 George
