Dear Jan, dear All,
I would like to ask your opinion about RRQ/RCF operation between a Cisco TCS and a GnuGK 3.1. When GW mode is used, TCS sends out and RCF containing a H.323 ID, an E.164 and several gateway wildcard prefixes.
GnuGk sends back a general RCF message, only confirming the H.323 ID sent by TCS.
Thus, at the TCS side, the registration is not complete, because TCS expects all the required H.323IDs/E.164s to be confirmed by gatekeeper. Cisco's statement on this, that GnuGK's response is not according to standards.
What do you think about it?
In addition, since TCS percieves that registretion is not completely confirmed, it keeps sending out RRQs very frequently, at a rate 1-2x/sec. I think it is not normal. We are currently tracking down this with Cisco dev.
This is how a TCS RRQ looks like:
